Protein: Rho GTPase-activating protein 32 (Brain-specific Rho GTPase-activating protein) (GAB-associated Cdc42/Rac GTPase-activating protein) (GC-GAP) (Rho-type GTPase-activating protein 32) (Rho/Cdc42/Rac GTPase-activating protein RICS) (RhoGAP involved in the beta-catenin-N-cadherin and NMDA receptor signaling) (p200RhoGAP) (p250GAP) (Q811P8)
Organism: Mus musculus (Mouse)
Function: GTPase-activating protein (GAP) promoting GTP hydrolysis on RHOA, CDC42 and RAC1 small GTPases. May be involved in the differentiation of neuronal cells during the formation of neurite extensions. Involved in NMDA receptor activity-dependent actin reorganization in dendritic spines. May mediate cross-talks between Ras- and Rho-regulated signaling pathways in cell growth regulation. Isoform 2 has higher GAP activity.
Subcellular location: Postsynaptic density {ECO:0000269|PubMed:12531901, ECO:0000269|PubMed:27609886}. Cell projection, dendritic spine {ECO:0000269|PubMed:12531901}. Cytoplasm, cell cortex {ECO:0000250|UniProtKB:A7KAX9}. Endosome membrane {ECO:0000269|PubMed:17663722}. Golgi apparatus membrane {ECO:0000269|PubMed:17663722}. Endoplasmic reticulum membrane {ECO:0000269|PubMed:17663722}. Membrane {ECO:0000250|UniProtKB:A7KAX9}. Note=Association to membrane via PX domain (By similarity). Associated with cortical actin in undifferentiated neuroblastoma cells, but localized to dendritic spine and postsynaptic density after differentiation (PubMed:12531901). Colocalizes with EGFR at the cell membrane upon EGF treatment (By similarity). Colocalizes with GAB2 at the cell membrane (By similarity). {ECO:0000250|UniProtKB:A7KAX9, ECO:0000269|PubMed:12531901}.
