Beta-spectrin pleckstrin homology (PH) domain; ARHGAP family genes encode Rho/Rac/Cdc42-like GTPase activating proteins with RhoGAP domain. The ARHGAP members here all have a PH domain upstream of their C-terminal RhoGAP domain. Some have additional N-terminal SH3 and WW domains. The members here include: ARHGAP9, ARHGAP12, ARHGAP15, and ARHGAP27. ARHGAP27 and ARHGAP12 shared the common-domain structure, consisting of SH3, WW, PH, and RhoGAP domains. The PH domain of ArhGAP9 employs a non-canonical phosphoinositide binding mechanism, a variation of the spectrin- Ins(4,5)P2-binding mode, that gives rise to a unique PI binding profile, namely a preference for both PI(4,5)P2 and the PI 3-kinase products PI(3,4,5)P3 and PI(3,4)P2. This lipid binding mechanism is also employed by the PH domain of Tiam1 and Slm1. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

RhoGAP_fRGD1: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of fungal RGD1-like proteins. Yeast Rgd1 is a GAP protein for Rho3 and Rho4 and plays a role in low-pH response. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway. GTPases generally have a low intrinsic GTPase hydrolytic activity but there are family-specific groups of GAPs that enhance the rate of GTP hydrolysis by several orders of magnitude.

RhoGAP_Graf: GTPase-activator protein (GAP) domain for Rho-like GTPases found in GRAF (GTPase regulator associated with focal adhesion kinase); Graf is a multi-domain protein, containing SH3 and PH domains, that binds focal adhesion kinase and influences cytoskeletal changes mediated by Rho proteins. Graf exhibits GAP activity toward RhoA and Cdc42, but only weakly activates Rac1. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway.

RhoGAP_Bcr: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of Bcr (breakpoint cluster region protein)-like proteins. Bcr is a multidomain protein with a variety of enzymatic functions. It contains a RhoGAP and a Rho GEF domain, a Ser/Thr kinase domain, an N-terminal oligomerization domain, and a C-terminal PDZ binding domain, in addition to PH and C2 domains. Bcr is a negative regulator of: i) RacGTPase, via the Rho GAP domain, ii) the Ras-Raf-MEK-ERK pathway, via phosphorylation of the Ras binding protein AF-6, and iii) the Wnt signaling pathway through binding beta-catenin. Bcr can form a complex with beta-catenin and Tcf1. The Wnt signaling pathway is involved in cell proliferation, differentiation, and cell renewal. Bcr was discovered as a fusion partner of Abl. The Bcr-Abl fusion is characteristic for a large majority of chronic myelogenous leukemias (CML). Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway. GTPases generally have a low intrinsic GTPase hydrolytic activity but there are family-specific groups of GAPs that enhance the rate of GTP hydrolysis by several orders of magnitude.

RhoGAP_CdGAP: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of CdGAP-like proteins; CdGAP contains an N-terminal RhoGAP domain and a C-terminal proline-rich region, and it is active on both Cdc42 and Rac1 but not RhoA. CdGAP is recruited to focal adhesions via the interaction with the scaffold protein actopaxin (alpha-parvin). Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway.

RhoGAP_nadrin: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of Nadrin-like proteins. Nadrin, also named Rich-1, has been shown to be involved in the regulation of Ca2+-dependent exocytosis in neurons and recently has been implicated in tight junction maintenance in mammalian epithelium. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway. GTPases generally have a low intrinsic GTPase hydrolytic activity but there are family-specific groups of GAPs that enhance the rate of GTP hydrolysis by several orders of magnitude.

RhoGAP-p50rhoGAP: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of p50RhoGAP-like proteins; p50RhoGAP, also known as RhoGAP-1, contains a C-terminal RhoGAP domain and an N-terminal Sec14 domain which binds phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3). It is ubiquitously expressed and preferentially active on Cdc42. This subgroup also contains closely related ARHGAP8. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway.

RhoGAP_ARAP: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain present in ARAPs. ARAPs (also known as centaurin deltas) contain, besides the RhoGAP domain, an Arf GAP, ankyrin repeat ras-associating, and PH domains. Since their ArfGAP activity is PIP3-dependent, ARAPs are considered integration points for phosphoinositide, Arf and Rho signaling. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway.

RhoGAP_myosin_IXB: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain present in myosins IXB. Class IX myosins contain a characteristic head domain, a neck domain and a tail domain which contains a C6H2-zinc binding motif and a Rho-GAP domain. Class IX myosins are single-headed, processive myosins that are partly cytoplasmic, and partly associated with membranes and the actin cytoskeleton. Class IX myosins are implicated in the regulation of neuronal morphogenesis and function of sensory systems, like the inner ear. There are two major isoforms, myosin IXA and IXB with several splice variants, which are both expressed in developing neurons Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway.
