The RAS gene produces a protein (Ras) that acts as a molecular switch in cell signaling pathways, typically promoting cell growth and proliferation when bound to GTP (guanosine triphosphate). To turn this signal off, the Ras protein must hydrolyze its bound GTP to GDP (guanosine diphosphate). This hydrolysis is significantly accelerated by GTPase activating proteins (GAPs), which inhibit the active state of the Ras protein by promoting its deactivation.
