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. 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.

Src homology 3 domain of Rho GTPase-activating proteins 32 and 33, and similar proteins; Members of this family contain N-terminal PX and Src Homology 3 (SH3) domains, a central Rho GAP domain, and C-terminal extensions. RhoGAPs (or ARHGAPs) bind to Rho proteins and enhance the hydrolysis rates of bound GTP. ARHGAP32 is also called RICS, PX-RICS, p250GAP, or p200RhoGAP. It is a Rho GTPase-activating protein for Cdc42 and Rac1, and is implicated in the regulation of postsynaptic signaling and neurite outgrowth. PX-RICS, a variant of RICS that contain PX and SH3 domains, is the main isoform expressed during neural development. It is involved in neural functions including axon and dendrite extension, postnatal remodeling, and fine-tuning of neural circuits during early brain development. ARHGAP33, also called sorting nexin 26 or TCGAP (Tc10/CDC42 GTPase-activating protein), is widely expressed in the brain where it is involved in regulating the outgrowth of axons and dendrites and is regulated by the protein tyrosine kinase Fyn. It is translocated to the plasma membrane in adipocytes in response to insulin and may be involved in the regulation of insulin-stimulated glucose transport. 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.

PX-RICS is the main isoform expressed during neural development. It is involved in neural functions including axon and dendrite extension, postnatal remodeling, and fine-tuning of neural circuits during early brain development. The PX domain of PX-RICS specifically binds phosphatidylinositol 3-phosphate (PI3P), PI4P, and PI5P. TCGAP is widely expressed in the brain where it is involved in regulating the outgrowth of axons and dendrites and is regulated by the protein tyrosine kinase Fyn. The PX domain is involved in targeting of proteins to PI-enriched membranes, and may also be involved in protein-protein interaction.

The phosphoinositide binding Phox Homology domain of Tc10/Cdc42 GTPase-activating protein; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions such as cell signaling, vesicular trafficking, protein sorting, and lipid modification, among others. TCGAP (Tc10/Cdc42 GTPase-activating protein) contains N-terminal PX and Src Homology 3 (SH3) domains, a central Rho GAP domain, and C-terminal proline-rich regions. It is widely expressed in the brain where it is involved in regulating the outgrowth of axons and dendrites and is regulated by the protein tyrosine kinase Fyn. It interacts with cdc42 and TC10beta through its GAP domain and with phosphatidylinositol-(4,5)-bisphosphate [PI(4,5)P2] through its PX domain. It is translocated to the plasma membrane in adipocytes in response to insulin and may be involved in the regulation of insulin-stimulated glucose transport. TCGAP has also been named sorting nexins 26 (SNX26). SNXs make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic 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_chimaerin: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of chimaerins. Chimaerins are a family of phorbolester- and diacylglycerol-responsive GAPs specific for the Rho-like GTPase Rac. Chimaerins exist in two alternative splice forms that each contain a C-terminal GAP domain, and a central C1 domain which binds phorbol esters, inducing a conformational change that activates the protein; one splice form is lacking the N-terminal Src homology-2 (SH2) domain. 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.

Src homology 3 domain of Rho GTPase-activating proteins 32 and 33, and similar proteins; Members of this family contain N-terminal PX and Src Homology 3 (SH3) domains, a central Rho GAP domain, and C-terminal extensions. RhoGAPs (or ARHGAPs) bind to Rho proteins and enhance the hydrolysis rates of bound GTP. ARHGAP32 is also called RICS, PX-RICS, p250GAP, or p200RhoGAP. It is a Rho GTPase-activating protein for Cdc42 and Rac1, and is implicated in the regulation of postsynaptic signaling and neurite outgrowth. PX-RICS, a variant of RICS that contain PX and SH3 domains, is the main isoform expressed during neural development. It is involved in neural functions including axon and dendrite extension, postnatal remodeling, and fine-tuning of neural circuits during early brain development. ARHGAP33, also called sorting nexin 26 or TCGAP (Tc10/CDC42 GTPase-activating protein), is widely expressed in the brain where it is involved in regulating the outgrowth of axons and dendrites and is regulated by the protein tyrosine kinase Fyn. It is translocated to the plasma membrane in adipocytes in response to insulin and may be involved in the regulation of insulin-stimulated glucose transport. 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.

RhoGAP_GMIP_PARG1: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of GMIP (Gem interacting protein) and PARG1 (PTPL1-associated RhoGAP1). GMIP plays important roles in neurite growth and axonal guidance, and interacts with Gem, a member of the RGK subfamily of the Ras small GTPase superfamily, through the N-terminal half of the protein. GMIP contains a C-terminal RhoGAP domain. GMIP inhibits RhoA function, but is inactive towards Rac1 and Cdc41. PARG1 interacts with Rap2, also a member of the Ras small GTPase superfamily whose exact function is unknown, and shows strong preference for Rho. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound.

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. 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_MgcRacGAP: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain present in MgcRacGAP proteins. MgcRacGAP plays an important dual role in cytokinesis: i) it is part of centralspindlin-complex, together with the mitotic kinesin MKLP1, which is critical for the structure of the central spindle by promoting microtuble bundling. ii) after phosphorylation by aurora B MgcRacGAP becomes an effective regulator of RhoA and plays an important role in the assembly of the contractile ring and the initiation of cytokinesis. MgcRacGAP-like proteins contain a N-terminal C1-like domain, and a C-terminal RhoGAP domain. 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.
