class VII myosin, motor domain; These monomeric myosins have been associated with functions in sensory systems such as vision and hearing. Mammalian myosin VII has a tail with 2 MyTH4 domains, 2 FERM domains, and a SH3 domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain 1, F1 sub-domain, found in Myosin-VIIa, Myosin-VIIb, and similar proteins; This family includes two nontraditional members of the myosin superfamily, myosin-VIIa and myosin-VIIb. Myosin-VIIa, also termed myosin-7a (Myo7a), has been implicated in the structural organization of hair bundles at the apex of sensory hair cells (SHCs) where it serves mechanotransduction in the process of hearing and balance. Mutations in the MYO7A gene may be associated with Usher Syndrome type 1B (USH1B) and nonsyndromic hearing loss (DFNB2, DFNA11). Myosin-VIIb, also termed myosin-7b (Myo7b), is a high duty ratio motor adapted for generating and maintaining tension. It associates with harmonin and ANKS4B to form a stable ternary complex for anchoring microvilli tip-link cadherins. Like other unconventional myosins, myosin-VII is composed of a conserved motor head, a neck region and a tail region containing two MyTH4 domains, a SH3 domain, and two FERM domains. The FERM domain is made up of three sub-domains, F1, F2, and F3. The family corresponds to the F1 sub-domain of the first FERM domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

FERM domain C-lobe, repeat 2, of Myosin VII (MyoVII, Myo7); MyoVII, a MyTH-FERM myosin, is an actin-based motor protein essential for a variety of biological processes in the actin cytoskeleton function. Mutations in MyoVII leads to problems in sensory perception: deafness and blindness in humans (Usher Syndrome), retinal defects and deafness in mice (shaker 1), and aberrant auditory and vestibular function in zebrafish. Myosin VIIAs have plus (barbed) end-directed motor activity on actin filaments and a characteristic actin-activated ATPase activity. MyoVII consists of a conserved spectrin-like, SH3 subdomain N-terminal region, a motor/head region, a neck made of 4-5 IQ motifs, and a tail consisting of a coiled-coil domain, followed by a tandem repeat of myosin tail homology 4 (MyTH4) domains and partial FERM domains that are separated by an SH3 subdomain and are thought to mediate dimerization and binding to other proteins or cargo. Members include: MyoVIIa, MyoVIIb, and MyoVII members that do not have distinct myosin VIIA and myosin VIIB genes. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

Src Homology 3 domain superfamily; Src Homology 3 (SH3) domains are protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. Thus, they are referred to as proline-recognition domains (PRDs). SH3 domains are less selective and show more diverse specificity compared to other PRDs. They have been shown to bind peptide sequences that lack the PxxP motif; examples include the PxxDY motif of Eps8 and the RKxxYxxY sequence in SKAP55. SH3 domain containing proteins play versatile and diverse roles in the cell, including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies, among others. Many members of this superfamily are adaptor proteins that associate with a number of protein partners, facilitating complex formation and signal transduction.

Selection of members of the seed alignment and criteria for setting scoring cutoffs are based largely conserved operon struction. //The Tol-Pal complex is required for maintaining outer membrane integrity. Also involved in transport (uptake) of colicins and filamentous DNA, and implicated in pathogenesis. Transport is energized by the proton motive force.

UDM1 (ubiquitin-dependent DSB recruitment module 1) found in RING finger proteins RNF168, RNF169 and similar proteins; This model represents the UDM1 (ubiquitin-dependent double-strand break [DSB] recruitment module 1) found in RING finger proteins, RNF168 and RNF169. RNF168 is an E3 ubiquitin-protein ligase that promotes non-canonical K27 ubiquitination to signal DNA damage. It functions, together with RNF8, as a DNA damage response (DDR) factor that promotes a series of ubiquitylation events on substrates such as H2A and H2AX. With H2AK13/15 ubiquitylation, it facilitates recruitment of repair factors p53-binding protein 1 (53BP1) or the RAP80-BRCA1 complex to sites of double-strand breaks (DSBs), and inhibits homologous recombination (HR) in cells deficient in the tumor suppressor BRCA1. RNF168 also promotes H2A neddylation, which antagonizes ubiquitylation of H2A and regulates DNA damage repair. In addition, RNF168 forms a functional complex with RAD6A or RAD6B during the DNA damage response. RNF169 is an uncharacterized E3 ubiquitin-protein ligase paralogous to RNF168. It functions as a negative regulator of the DNA damage signaling cascade. RNF169 recognizes polyubiquitin structures but does not itself contribute to double-strand break (DSB)-induced chromatin ubiquitylation. It contributes to the regulation of DSB repair pathway utilization via functionally competing with recruiting repair factors, 53BP1 and RAP80-BRCA1, for association with RNF168-modified chromatin, independent of its catalytic activity, limiting the magnitude of the RNF8/RNF168-dependent signaling response to DSBs. The UDM1 domain comprises LRM1 (LR motif 1), UMI (ubiquitin-interacting motif [UIM]- and MIU-related UBD) and MIU1 (motif interacting with ubiquitin 1). Mutations of Ub-interacting residues in UDM1 have little effect on the accumulation of RNF168 to DSB sites, suggesting that it may not be the main site of binding ubiquitylated and polyubiquitylated targets.

PspA/IM30 family; This family includes PspA a protein that suppresses sigma54-dependent transcription. The PspA protein, a negative regulator of the Escherichia coli phage shock psp operon, is produced when virulence factors are exported through secretins in many Gram-negative pathogenic bacteria and its homolog in plants, VIPP1, plays a critical role in thylakoid biogenesis, essential for photosynthesis. Activation of transcription by the enhancer-dependent bacterial sigma(54) containing RNA polymerase occurs through ATP hydrolysis-driven protein conformational changes enabled by activator proteins that belong to the large AAA(+) mechanochemical protein family. It has been shown that PspA directly and specifically acts upon and binds to the AAA(+) domain of the PspF transcription activator.

class VII myosin, motor domain; These monomeric myosins have been associated with functions in sensory systems such as vision and hearing. Mammalian myosin VII has a tail with 2 MyTH4 domains, 2 FERM domains, and a SH3 domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class VI myosin, motor domain; Myosin VI is a monomeric myosin, which moves towards the minus-end of actin filaments, in contrast to most other myosins which moves towards the plus-end of actin filaments. It is thought that myosin VI, unlike plus-end directed myosins, does not use a pure lever arm mechanism, but instead steps with a mechanism analogous to the kinesin neck-linker uncoupling model. It has been implicated in a myriad of functions including: the transport of cytoplasmic organelles, maintenance of normal Golgi morphology, endocytosis, secretion, cell migration, border cell migration during development, and in cancer metastasis playing roles in deafness and retinal development among others. While how this is accomplished is largely unknown there are several interacting proteins that have been identified such as disabled homolog 2 (DAB2), GIPC1, synapse-associated protein 97 (SAP97; also known as DLG1) and optineurin, which have been found to target myosin VI to different cellular compartments.

The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. C-terminal to their motor domain these myosins have a MyTH4-FERM protein domain combination. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 11, motor domain; Myosin motor domain of smooth muscle myosin heavy chain 11 (also called SMMHC, SMHC). The gene product is a subunit of a hexameric protein that consists of two heavy chain subunits and two pairs of non-identical light chain subunits. It functions as a major contractile protein, converting chemical energy into mechanical energy through the hydrolysis of ATP. The gene encoding a human ortholog of rat NUDE1 is transcribed from the reverse strand of this gene, and its 3' end overlaps with that of the latter. Inversion of the MYH11 locus is one of the most frequent chromosomal aberrations found in acute myeloid leukemia. Alternative splicing generates isoforms that are differentially expressed, with ratios changing during muscle cell maturation. Mutations in MYH11 have been described in individuals with thoracic aortic aneurysms leading to acute aortic dissections with patent ductus arteriosus. MYH11 mutations are also thought to contribute to human colorectal cancer and are also associated with Peutz-Jeghers syndrome. The mutations found in human intestinal neoplasia result in unregulated proteins with constitutive motor activity, similar to the mutant myh11 zebrafish. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 7, motor domain; Myosin motor domain of beta (or slow) type I cardiac muscle myosin heavy chain 7 (also called CMH1, MPD1, and CMD1S). Muscle myosin is a hexameric protein containing 2 heavy chain subunits, 2 alkali light chain subunits, and 2 regulatory light chain subunits. It is expressed predominantly in normal human ventrical and in skeletal muscle tissues rich in slow-twitch type I muscle fibers.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain 1, F1 sub-domain, found in Myosin-VIIa, Myosin-VIIb, and similar proteins; This family includes two nontraditional members of the myosin superfamily, myosin-VIIa and myosin-VIIb. Myosin-VIIa, also termed myosin-7a (Myo7a), has been implicated in the structural organization of hair bundles at the apex of sensory hair cells (SHCs) where it serves mechanotransduction in the process of hearing and balance. Mutations in the MYO7A gene may be associated with Usher Syndrome type 1B (USH1B) and nonsyndromic hearing loss (DFNB2, DFNA11). Myosin-VIIb, also termed myosin-7b (Myo7b), is a high duty ratio motor adapted for generating and maintaining tension. It associates with harmonin and ANKS4B to form a stable ternary complex for anchoring microvilli tip-link cadherins. Like other unconventional myosins, myosin-VII is composed of a conserved motor head, a neck region and a tail region containing two MyTH4 domains, a SH3 domain, and two FERM domains. The FERM domain is made up of three sub-domains, F1, F2, and F3. The family corresponds to the F1 sub-domain of the first FERM domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

FERM domain C-lobe, repeat 2, of Myosin VII (MyoVII, Myo7); MyoVII, a MyTH-FERM myosin, is an actin-based motor protein essential for a variety of biological processes in the actin cytoskeleton function. Mutations in MyoVII leads to problems in sensory perception: deafness and blindness in humans (Usher Syndrome), retinal defects and deafness in mice (shaker 1), and aberrant auditory and vestibular function in zebrafish. Myosin VIIAs have plus (barbed) end-directed motor activity on actin filaments and a characteristic actin-activated ATPase activity. MyoVII consists of a conserved spectrin-like, SH3 subdomain N-terminal region, a motor/head region, a neck made of 4-5 IQ motifs, and a tail consisting of a coiled-coil domain, followed by a tandem repeat of myosin tail homology 4 (MyTH4) domains and partial FERM domains that are separated by an SH3 subdomain and are thought to mediate dimerization and binding to other proteins or cargo. Members include: MyoVIIa, MyoVIIb, and MyoVII members that do not have distinct myosin VIIA and myosin VIIB genes. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

Src Homology 3 domain of Myosin VIIa and similar proteins; Myo7A is an uncoventional myosin that is involved in organelle transport. It is required for sensory function in both Drosophila and mammals. Mutations in the Myo7A gene cause both syndromic deaf-blindness [Usher syndrome I (USH1)] and nonsyndromic (DFNB2 and DFNA11) deafness in humans. It contains an N-terminal motor domain, light chain-binding IQ motifs, a coiled-coil region for heavy chain dimerization, and a tail consisting of a pair of MyTH4-FERM tandems separated by a SH3 domain. SH3 domains bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs; they play a role in the regulation of enzymes by intramolecular interactions, changing the subcellular localization of signal pathway components and mediate multiprotein complex assemblies.

Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

UDM1 (ubiquitin-dependent DSB recruitment module 1) found in RING finger proteins RNF168, RNF169 and similar proteins; This model represents the UDM1 (ubiquitin-dependent double-strand break [DSB] recruitment module 1) found in RING finger proteins, RNF168 and RNF169. RNF168 is an E3 ubiquitin-protein ligase that promotes non-canonical K27 ubiquitination to signal DNA damage. It functions, together with RNF8, as a DNA damage response (DDR) factor that promotes a series of ubiquitylation events on substrates such as H2A and H2AX. With H2AK13/15 ubiquitylation, it facilitates recruitment of repair factors p53-binding protein 1 (53BP1) or the RAP80-BRCA1 complex to sites of double-strand breaks (DSBs), and inhibits homologous recombination (HR) in cells deficient in the tumor suppressor BRCA1. RNF168 also promotes H2A neddylation, which antagonizes ubiquitylation of H2A and regulates DNA damage repair. In addition, RNF168 forms a functional complex with RAD6A or RAD6B during the DNA damage response. RNF169 is an uncharacterized E3 ubiquitin-protein ligase paralogous to RNF168. It functions as a negative regulator of the DNA damage signaling cascade. RNF169 recognizes polyubiquitin structures but does not itself contribute to double-strand break (DSB)-induced chromatin ubiquitylation. It contributes to the regulation of DSB repair pathway utilization via functionally competing with recruiting repair factors, 53BP1 and RAP80-BRCA1, for association with RNF168-modified chromatin, independent of its catalytic activity, limiting the magnitude of the RNF8/RNF168-dependent signaling response to DSBs. The UDM1 domain comprises LRM1 (LR motif 1), UMI (ubiquitin-interacting motif [UIM]- and MIU-related UBD) and MIU1 (motif interacting with ubiquitin 1). Mutations of Ub-interacting residues in UDM1 have little effect on the accumulation of RNF168 to DSB sites, suggesting that it may not be the main site of binding ubiquitylated and polyubiquitylated targets.

These myosin-like proteins contain an N-terminal motor/head region and a C-terminal tail consisting of two myosin tail homology 4 (MyTH4) and twos FERM domains. In myoX the FERM domain forms a supramodule with its MyTH4 domain which binds to the negatively charged E-hook region in the tails of alpha- and beta-tubulin forming a proposed motorized link between actin filaments and microtubules and a similar thing might happen in these myosins.

FERM domain C-lobe of Myosin XV (MyoXV/Myo15); MyoXV, a MyTH-FERM myosin, are actin-based motor proteins essential for a variety of biological processes in actin cytoskeleton function. Specifically MyoXV functions in the actin organization in hair cells of the organ of Corti. Mutations in Human MyoXVa causes non-syndromic deafness, DFNB3 and the mouse shaker-2 mutation. MyoXV consists of a N-terminal motor/head region, a neck made of 1-3 IQ motifs, and a tail that consists of either a myosin tail homology 4 (MyTH4) domains, followed by an SH3 domain, and a MyTH-FERM domains as in rat Myo15 or two MyTH-FERM domains separated by a SH3 domain as in human Myo15A. The MyTH-FERM domains are thought to mediate dimerization and binding to other proteins or cargo.

FERM domain C-lobe/F3 of Talin; Talin (also called filopodin) plays an important role in initiating actin filament growth in motile cell protrusions. It is responsible for linking the cytoplasmic domains of integrins to the actin-based cytoskeleton, and is involved in vinculin, integrin and actin interactions. At the leading edge of motile cells, talin colocalises with the hyaluronan receptor layilin in transient adhesions, some of which become more stable focal adhesions (FA). During this maturation process, layilin is replaced with integrins, where localized production of PI(4,5)P(2) by type 1 phosphatidyl inositol phosphate kinase type 1gamma (PIPK1gamma) is thought to play a role in FA assembly. Talins are composed of a N-terminal region FERM domain which us made up of 3 subdomains (N, alpha-, and C-lobe; or- A-lobe, B-lobe, and C-lobe; or F1, F2, and F3) connected by short linkers, a talin rod which binds vinculin, and a conserved C-terminal region with actin- and integrin-binding sites. There are 2 additional actin-binding domains, one in the talin rod and the other in the FERM domain. Both the F2 and F3 FERM subdomains contribute to F-actin binding. Subdomain F3 of the FERM domain contains overlapping binding sites for integrin cytoplasmic domains and for the type 1 gamma isoform of PIP-kinase (phosphatidylinositol 4-phosphate 5-kinase). The FERM domain has a cloverleaf tripart structure . F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

TolA protein; TolA couples the inner membrane complex of itself with TolQ and TolR to the outer membrane complex of TolB and OprL (also called Pal). Most of the length of the protein consists of low-complexity sequence that may differ in both length and composition from one species to another, complicating efforts to discriminate TolA (the most divergent gene in the tol-pal system) from paralogs such as TonB. Selection of members of the seed alignment and criteria for setting scoring cutoffs are based largely conserved operon struction. //The Tol-Pal complex is required for maintaining outer membrane integrity. Also involved in transport (uptake) of colicins and filamentous DNA, and implicated in pathogenesis. Transport is energized by the proton motive force. TolA is an inner membrane protein that interacts with periplasmic TolB and with outer membrane porins ompC, phoE and lamB. [Transport and binding proteins, Other, Cellular processes, Pathogenesis]

It is associated with the mitochondrial outer membrane, and over-expression leads to reduction in mitochondrial motility whereas lack of it enhances mitochondrial movement. The activity appears to be mediated through binding the mitochondria to the actin intermediate filaments (IFs). The family is in the trichohyalin-plectin-homology domain.

Src Homology 3 domain of the p85beta regulatory subunit of Class IA Phosphatidylinositol 3-kinases; Class I PI3Ks convert PtdIns(4,5)P2 to the critical second messenger PtdIns(3,4,5)P3. They are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (out of four isoforms) and one of several regulatory subunits. Class IA PI3Ks associate with the p85 regulatory subunit family, which contains SH3, RhoGAP, and SH2 domains. The p85 subunits recruit the PI3K p110 catalytic subunit to the membrane, where p110 phosphorylates inositol lipids. Vertebrates harbor two p85 isoforms, called alpha and beta. In addition to regulating the p110 subunit, p85beta binds CD28 and may be involved in the activation and differentiation of antigen-stimulated T cells. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

The F-type ATP synthases (FoF1-ATPase) consist of two structural domains: the F1 (assembly factor one) complex containing the soluble catalytic core, and the Fo (oligomycin sensitive factor) complex containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. F1 is composed of alpha (or A), beta (B), gamma (C), delta (D) and epsilon (E) subunits with a stoichiometry of 3:3:1:1:1, while Fo consists of the three subunits a, b, and c (1:2:10-14). An oligomeric ring of 10-14 c subunits (c-ring) make up the Fo rotor. The flux of protons through the ATPase channel (Fo) drives the rotation of the c-ring, which in turn is coupled to the rotation of the F1 complex gamma subunit rotor due to the permanent binding between the gamma and epsilon subunits of F1 and the c-ring of Fo. The F-ATP synthases are primarily found in the inner membranes of eukaryotic mitochondria, in the thylakoid membranes of chloroplasts or in the plasma membranes of bacteria. The F-ATP synthases are the primary producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts). Alternatively, under conditions of low driving force, ATP synthases function as ATPases, thus generating a transmembrane proton or Na(+) gradient at the expense of energy derived from ATP hydrolysis.

Ezrin was first identified as a constituent of microvilli, radixin as a barbed, end-capping actin-modulating protein from isolated junctional fractions, and moesin as a heparin binding protein. A tumour suppressor molecule responsible for neurofibromatosis type 2 (NF2) is highly similar to ERM proteins and has been designated merlin (moesin-ezrin-radixin-like protein). ERM molecules contain 3 domains, an N-terminal globular domain, an extended alpha-helical domain and a charged C-terminal domain (pfam00769). Ezrin, radixin and merlin also contain a polyproline linker region between the helical and C-terminal domains. The N-terminal domain is highly conserved and is also found in merlin, band 4.1 proteins and members of the band 4.1 superfamily, designated the FERM domain. ERM proteins crosslink actin filaments with plasma membranes. They co-localize with CD44 at actin filament plasma membrane interaction sites, associating with CD44 via their N-terminal domains and with actin filaments via their C-terminal domains. This is the alpha-helical domain, which is involved in intramolecular masking of protein-protein interaction sites, regulating the activity of this proteins.

It plays a role in regulating the actin cytoskeleton and colocalizes with F-actin, cortactin, VASP, and vinculin. BAIAP2L1 expression leads to the formation of short actin bundles, distinct from filopodia-like protrusions induced by the expression of the related protein IRSp53. IRTKS mediates the recruitment of effector proteins Tir and EspFu, which regulate host cell actin reorganization, to bacterial attachment sites. It contains an N-terminal IMD or Inverse-Bin/Amphiphysin/Rvs (I-BAR) domain, an SH3 domain, and a WASP homology 2 (WH2) actin-binding motif at the C-terminus. The SH3 domain of IRTKS has been shown to bind the proline-rich C-terminus of EspFu.

calmodulin binding domain found in unconventional myosin-VI and similar proteins; Myosins, which are actin-based motor molecules with ATPase activity, include unconventional myosins that serve in intracellular movements. Myosin-VI, also called unconventional myosin-6 (MYO6), is a reverse-direction motor protein that moves towards the minus-end of actin filaments. It is required for the structural integrity of the Golgi apparatus via the p53-dependent pro-survival pathway. Myosin-VI appears to be involved in a very early step of clathrin-mediated endocytosis in polarized epithelial cells. It modulates RNA polymerase II-dependent transcription. As part of the DISP (DOCK7-Induced Septin disPlacement) complex, Myosin-VI may regulate the association of septins with actin and thereby regulate the actin cytoskeleton. Myosin-VI is encoded by gene MYO6, the human homolog of the gene responsible for deafness in Snell's waltzer mice. It is mutated in autosomal dominant non-syndromic hearing loss. This family also includes Drosophila melanogaster unconventional myosin VI Jaguar (Jar; also called myosin heavy chain 95F (Mhc95F), or 95F MHC), which is a motor protein necessary for the morphogenesis of epithelial tissues during Drosophila development. Jar is required for basal protein targeting and correct spindle orientation in mitotic neuroblasts. It contributes to synaptic transmission and development at the Drosophila neuromuscular junction. Together with CLIP-190 (CAP-Gly domain-containing/cytoplasmic linker protein 190), Jar may coordinate the interaction between the actin and microtubule cytoskeleton. Jar may link endocytic vesicles to microtubules and possibly be involved in transport in the early embryo and in the dynamic process of dorsal closure; its function is believed to change during the life cycle. This model corresponds to the calmodulin (CaM) binding domain (CBD), which consists of three subdomains: a unique insert (Insert 2 or Ins2), an IQ motif, and a proximal tail domain (PTD, also known as lever arm extension or LAE).

Activation of transcription by the enhancer-dependent bacterial sigma(54) containing RNA polymerase occurs through ATP hydrolysis-driven protein conformational changes enabled by activator proteins that belong to the large AAA(+) mechanochemical protein family. It has been shown that PspA directly and specifically acts upon and binds to the AAA(+) domain of the PspF transcription activator.

The conserved domain common to the SPFH superfamily has also been referred to as the Band 7 domain. Many superfamily members are associated with lipid rafts. Individual proteins of the SPFH superfamily may cluster to form membrane microdomains which may in turn recruit multiprotein complexes. Microdomains formed from flotillin proteins may in addition be dynamic units with their own regulatory functions. Flotillins have been implicated in signal transduction, vesicle trafficking, cytoskeleton rearrangement and are known to interact with a variety of proteins. Stomatin interacts with and regulates members of the degenerin/epithelia Na+ channel family in mechanosensory cells of Caenorhabditis elegans and vertebrate neurons and participates in trafficking of Glut1 glucose transporters. Prohibitin may act as a chaperone for the stabilization of mitochondrial proteins. Prokaryotic HflK/C plays a role in the decision between lysogenic and lytic cycle growth during lambda phage infection. Flotillins have been implicated in the progression of prion disease, in the pathogenesis of neurodegenerative diseases such as Parkinson's and Alzheimer's disease and, in cancer invasion and metastasis. Mutations in the podocin gene give rise to autosomal recessive steroid resistant nephritic syndrome.

Src Homology 3 domain of Insulin Receptor tyrosine kinase Substrate p53; IRSp53 is also known as BAIAP2 (Brain-specific Angiogenesis Inhibitor 1-Associated Protein 2). It is a scaffolding protein that takes part in many signaling pathways including Cdc42-induced filopodia formation, Rac-mediated lamellipodia extension, and spine morphogenesis. IRSp53 exists as multiple splicing variants that differ mainly at the C-termini. One variant (T-form) is expressed exclusively in human breast cancer cells. The gene encoding IRSp53 is a putative susceptibility gene for Gilles de la Tourette syndrome. IRSp53 can also mediate the recruitment of effector proteins Tir and EspFu, which regulate host cell actin reorganization, to bacterial attachment sites. It contains an N-terminal IMD, a CRIB (Cdc42 and Rac interactive binding motif), an SH3 domain, and a WASP homology 2 (WH2) actin-binding motif at the C-terminus. The SH3 domain of IRSp53 has been shown to bind the proline-rich C-terminus of EspFu. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Src Homology 3 domain of the p85 regulatory subunit of Class IA Phosphatidylinositol 3-kinases; Class I PI3Ks convert PtdIns(4,5)P2 to the critical second messenger PtdIns(3,4,5)P3. They are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (out of four isoforms) and one of several regulatory subunits. Class IA PI3Ks associate with the p85 regulatory subunit family, which contains SH3, RhoGAP, and SH2 domains. The p85 subunits recruit the PI3K p110 catalytic subunit to the membrane, where p110 phosphorylates inositol lipids. Vertebrates harbor two p85 isoforms, called alpha and beta. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Src Homology 3 domain of Amphiphysin and related domains; Amphiphysins function primarily in endocytosis and other membrane remodeling events. They exist in several isoforms and mammals possess two amphiphysin proteins from distinct genes. Amphiphysin I proteins, enriched in the brain and nervous system, contain domains that bind clathrin, Adaptor Protein complex 2 (AP2), dynamin, and synaptojanin. They function in synaptic vesicle endocytosis. Human autoantibodies to amphiphysin I hinder GABAergic signaling and contribute to the pathogenesis of paraneoplastic stiff-person syndrome. Some amphiphysin II isoforms, also called Bridging integrator 1 (Bin1), are localized in many different tissues and may function in intracellular vesicle trafficking. In skeletal muscle, Bin1 plays a role in the organization and maintenance of the T-tubule network. Mutations in Bin1 are associated with autosomal recessive centronuclear myopathy. Amphiphysins contain an N-terminal BAR domain with an additional N-terminal amphipathic helix (an N-BAR), a variable central domain, and a C-terminal SH3 domain. The SH3 domain of amphiphysins bind proline-rich motifs present in binding partners such as dynamin, synaptojanin, and nsP3. It also belongs to a subset of SH3 domains that bind ubiquitin in a site that overlaps with the peptide binding site. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

TolA protein; TolA couples the inner membrane complex of itself with TolQ and TolR to the outer membrane complex of TolB and OprL (also called Pal). Most of the length of the protein consists of low-complexity sequence that may differ in both length and composition from one species to another, complicating efforts to discriminate TolA (the most divergent gene in the tol-pal system) from paralogs such as TonB. Selection of members of the seed alignment and criteria for setting scoring cutoffs are based largely conserved operon struction. //The Tol-Pal complex is required for maintaining outer membrane integrity. Also involved in transport (uptake) of colicins and filamentous DNA, and implicated in pathogenesis. Transport is energized by the proton motive force. TolA is an inner membrane protein that interacts with periplasmic TolB and with outer membrane porins ompC, phoE and lamB. [Transport and binding proteins, Other, Cellular processes, Pathogenesis]

Trichohyalin-plectin-homology domain; This family is a mixtrue of two different families of eukaryotic proteins. Trichoplein or mitostatin, was first defined as a meiosis-specific nuclear structural protein. It has since been linked with mitochondrial movement. It is associated with the mitochondrial outer membrane, and over-expression leads to reduction in mitochondrial motility whereas lack of it enhances mitochondrial movement. The activity appears to be mediated through binding the mitochondria to the actin intermediate filaments (IFs). The family is in the trichohyalin-plectin-homology domain.

Src Homology 3 domain of Insulin Receptor tyrosine kinase Substrate p53, Brain-specific Angiogenesis Inhibitor 1-Associated Protein 2 (BAIAP2)-Like proteins, and similar proteins; Proteins in this family include IRSp53, BAIAP2L1, BAIAP2L2, and similar proteins. They all contain an Inverse-Bin/Amphiphysin/Rvs (I-BAR) or IMD domain in addition to the SH3 domain. IRSp53, also known as BAIAP2, is a scaffolding protein that takes part in many signaling pathways including Cdc42-induced filopodia formation, Rac-mediated lamellipodia extension, and spine morphogenesis. IRSp53 exists as multiple splicing variants that differ mainly at the C-termini. BAIAP2L1, also called IRTKS (Insulin Receptor Tyrosine Kinase Substrate), serves as a substrate for the insulin receptor and binds the small GTPase Rac. It plays a role in regulating the actin cytoskeleton and colocalizes with F-actin, cortactin, VASP, and vinculin. IRSp53 and IRTKS also mediate the recruitment of effector proteins Tir and EspFu, which regulate host cell actin reorganization, to bacterial attachment sites. BAIAP2L2 co-localizes with clathrin plaques but its function has not been determined. The SH3 domains of IRSp53 and IRTKS have been shown to bind the proline-rich C-terminus of EspFu. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

5.16e-03
UDM1 (ubiquitin-dependent DSB recruitment module 1) domain found in RING finger protein 168; RING finger protein 168 (RNF168) is an E3 ubiquitin-protein ligase that promotes noncanonical K27 ubiquitination to signal DNA damage. Together with RNF8, RNF168 functions as a DNA damage response (DDR) factor that promotes a series of ubiquitylation events on substrates such as H2A and H2AX. With H2AK13/15 ubiquitylation, it facilitates recruitment of repair factors p53-binding protein 1 (53BP1) or the RAP80-BRCA1 complex to sites of double-strand breaks (DSBs), and inhibits homologous recombination (HR) in cells deficient in the tumor suppressor BRCA1. RNF168 also promotes H2A neddylation, which antagonizes ubiquitylation of H2A and regulates DNA damage repair. In addition, RNF168 forms a functional complex with RAD6A or RAD6B during the DNA damage response. This model corresponds to the UDM1 (ubiquitin-dependent double-strand break [DSB] recruitment module 1) domain of RNF168, which comprises LRM1 (LR motif 1), UMI (ubiquitin-interacting motif [UIM]- and MIU-related UBD) and MIU1 (motif interacting with ubiquitin 1). Mutations of Ub-interacting residues in UDM1 have little effect on the accumulation of RNF168 to DSB sites, suggesting that it may not be the main site of binding ubiquitylated and polyubiquitylated targets.
