45-154 3.11e-24

Calponin homology (CH) domain; The CH domain is found in both cytoskeletal proteins and signal transduction proteins. The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin have only a single copy.

calponin homology (CH) domain found in the transgelin family; The transgelin (TAGLN) family includes transgelin, transgelin-2 and transgelin-3. Transgelin, also called 22 kDa actin-binding protein, protein WS3-10, or smooth muscle protein 22-alpha (SM22-alpha), acts as an actin cross-linking/gelling protein that may be involved in calcium interactions and in regulating contractile properties of the cell. Transgelin-2, also called epididymis tissue protein Li 7e, or SM22-alpha homolog, acts as an actin-binding protein that induces actin gelation and regulates actin cytoskeleton. It may participate in the development and progression of multiple cancers. Transgelin-3, also called neuronal protein 22 (NP22), or neuronal protein NP25, may have a role in alcohol-related adaptations and may mediate regulatory signal transduction pathways in neurons. Members of this family contain a single copy of the CH domain. CH domains are actin filament (F-actin) binding motifs.

43-155 6.12e-36

calponin homology (CH) domain found in Drosophila melanogaster muscle-specific protein 20 (dMP20) and similar domains; This subfamily contains Drosophila melanogaster muscle-specific protein 20 (dMP20), Echinococcus granulosus myophilin, Dictyostelium discoideum Rac guanine nucleotide exchange factor B (also called Trix), and similar proteins. dMP20 is present only in the synchronous muscles of D. melanogaster. It may be involved in the system linking the nerve impulse with the contraction or the relaxation process. Trix is involved in the regulation of the late steps of the endocytic pathway. dMP20 contains a single copy of the CH domain, while Trix (triple CH-domain array exchange factor) contains three, two type 3 CH domains which are included in this model, and one type 1 CH domain that is not included in this subfamily, but is part of the superfamily. CH domains are actin filament (F-actin) binding motifs.

48-154 1.58e-26

calponin homology (CH) domain superfamily; CH domains are actin filament (F-actin) binding motifs, which may be present as a single copy or in tandem repeats (which increase binding affinity). They either function as autonomous actin binding motifs or serve a regulatory function. CH domains are found in cytoskeletal and signal transduction proteins, including actin-binding proteins like spectrin, alpha-actinin, dystrophin, utrophin, and fimbrin, as well as proteins essential for regulation of cell shape (cortexillins), and signaling proteins (Vav).

45-154 3.11e-24

Calponin homology (CH) domain; The CH domain is found in both cytoskeletal proteins and signal transduction proteins. The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin have only a single copy.

44-157 5.43e-24

calponin homology (CH) domain found in the calponin family; Calponin is an actin filament-associated regulatory protein expressed in smooth muscle and many types of non-muscle cells. There are three calponin isoforms, calponin-1, -2, -3. All of them are actin-binding proteins with functions in inhibiting actin-activated myosin ATPase and stabilizing the actin cytoskeleton. Calponin-1 is specifically expressed in smooth muscle cells and plays a role in fine-tuning smooth muscle contractility. Calponin-2 is expressed in both smooth muscle and non-muscle cells and regulates multiple actin cytoskeleton-based functions. Calponin-3 is expressed in the brain and participates in actin cytoskeleton-based activities in embryonic development and myogenesis. Members of this family contain a single copy of the CH domain. CH domains are actin filament (F-actin) binding motifs.

53-143 1.21e-13

calponin homology (CH) domain found in the IQ motif containing GTPase activating protein family; Members of the IQ motif containing GTPase activating protein (IQGAP) family are associated with the Ras GTP-binding protein and act as essential regulators of cytoskeletal function. There are three known IQGAP family members: IQGAP1, IQGAP2, and IQGAP3. They are multi-domain molecules having a calponin-homology (CH) domain which binds F-actin, IQGAP-specific repeats, a single WW domain, four IQ motifs that mediate interactions with calmodulin, and a RasGAP related domain that binds active Rho family GTPases. IQGAP1 negatively regulates Ras family GTPases by stimulating their intrinsic GTPase activity. It lacks GAP activity. Both IQGAP1 and IQGAP2 specifically bind to Cdc42 and Rac1, but not to RhoA. Despite similarities to part of the sequence of RasGAP, neither IQGAP1 nor IQGAP2 interacts with Ras. IQGAP3 regulates the organization of the cytoskeleton under the regulation of Rac1 and Cdc42 in neuronal cells. The depletion of IQGAP3 is shown to impair neurite or axon outgrowth in neuronal cells with disorganized cytoskeleton.

calponin homology (CH) domain found in VAV proteins; VAV proteins function both as cytoplasmic guanine nucleotide exchange factors (GEFs) for Rho GTPases and as scaffold proteins, and they play important roles in cell signaling by coupling cell surface receptors to various effector functions. They play key roles in processes that require cytoskeletal reorganization including immune synapse formation, phagocytosis, cell spreading, and platelet aggregation, among others. Vertebrates have three VAV proteins (VAV1, VAV2, and VAV3). VAV proteins contain several domains that enable their function: N-terminal calponin homology (CH), acidic, RhoGEF (also called Dbl-homologous or DH), Pleckstrin Homology (PH), C1 (zinc finger), SH2, and two SH3 domains. This model corresponds to the CH domain, an actin-binding domain which is present as a single copy in VAV proteins.

calponin homology (CH) domain found in LIM domain only protein 7 and similar proteins; This family includes LIM domain only protein 7 (LMO-7) and LIM and calponin homology domains-containing protein 1 (LIMCH1), and similar proteins. LMO-7, also called F-box only protein 20, or LOMP, is a transcription regulator for expression of many Emery-Dreifuss muscular dystrophy (EDMD)-relevant genes. It binds to alpha-actinin and AF6/afadin at adherens junctions for epithelial cell-cell adhesion. LIMCH1 acts as an actin stress fiber-associated protein that activates the non-muscle myosin IIa complex by promoting the phosphorylation of its regulatory subunit MRLC/MYL9. It positively regulates actin stress fiber assembly and stabilizes focal adhesions, and therefore negatively regulates cell spreading and cell migration. Members of this family contain a single copy of the CH domain at the N-terminus. CH domains are actin filament (F-actin) binding motifs.

77-153 8.35e-07

calponin homology (CH) domain found in the Pak Interactive eXchange factor family; Pak Interactive eXchange factor (PIX) proteins are Rho guanine nucleotide exchange factors (GEFs), which activate small GTPases by exchanging bound GDP for free GTP. They act as GEFs for both Cdc42 and Rac1, and have been implicated in cell motility, adhesion, neurite outgrowth, and cell polarity. Vertebrates contain two proteins from the PIX family, alpha-PIX and beta-PIX. Alpha-PIX, also called Rho guanine nucleotide exchange factor 6 (ARHGEF6), is localized in dendritic spines where it regulates spine morphogenesis. It controls dendritic length and spine density in the hippocampus. Mutations in the ARHGEF6 gene cause X-linked intellectual disability in humans. Beta-PIX, also called Rho guanine nucleotide exchange factor 7 (ARHGEF7), plays important roles in regulating neuroendocrine exocytosis, focal adhesion maturation, cell migration, synaptic vesicle localization, and insulin secretion. Both alpha-PIX and beta-PIX contain a single copy of the CH domain at the N-terminus. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in VAV1 protein; VAV1 is expressed predominantly in the hematopoietic system and it plays an important role in the development and activation of B and T cells. It is activated by tyrosine phosphorylation to function as a guanine nucleotide exchange factor (GEF) for Rho GTPases following cell surface receptor activation, triggering various effects such as cytoskeletal reorganization, transcription regulation, cell cycle progression, and calcium mobilization. It also serves as a scaffold protein and has been shown to interact with Ku70, Socs1, Janus kinase 2, SIAH2, S100B, Abl gene, ZAP-70, SLP76, and Syk, among others. VAV proteins contain several domains that enable their function: N-terminal calponin homology (CH), acidic, RhoGEF (also called Dbl-homologous or DH), Pleckstrin Homology (PH), C1 (zinc finger), SH2, and two SH3 domains. This model corresponds to the CH domain, an actin-binding domain which is present as a single copy in VAV1 protein.

first calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5; they cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in leucine-rich repeat and calponin homology domain-containing protein 3; Leucine-rich repeat and calponin homology domain-containing protein 3 (LRCH3) is part of the DISP (DOCK7-Induced Septin disPlacement) complex. It may regulate the association of septins with actin and thereby regulate the actin cytoskeleton. LRCH3 contains a single copy of the CH domain at the C-terminus. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in beta-Pak Interactive eXchange factor; Beta-Pak Interactive eXchange factor (beta-PIX), also called PAK-interacting exchange factor beta, Rho guanine nucleotide exchange factor 7 (ARHGEF7), p85, or Cool (Cloned out of Library)-1, activates small GTPases by exchanging bound GDP for free GTP. It acts as a GEF for both Cdc42 and Rac1, and plays important roles in regulating neuroendocrine exocytosis, focal adhesion maturation, cell migration, synaptic vesicle localization, and insulin secretion. Beta-PIX contains a single copy of the CH domain at its N-terminus. CH domains are actin filament (F-actin) binding motifs.
