Grit is an alias for the gene, Rho GTPase activating protein 32, in humans. Other names include: Rho GTPase-activating protein 32; Brain-specific Rho GTPase-activating protein; GAB-associated Cdc42/Rac GTPase-activating protein; GC-GAP; GTPase regulator interacting with TrkA; 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; GRIT; PX-RICS; RICS. The encoded protein has an amino acid length of 2087 and a mass of 230.5 kDa. Grit is a member of the PX domain-containing GAP family. This gene shares homology with other species, including: Mouse, Rat, Frog, Chicken.
