Rab (G-protein) - Wikipedia
The inherent GTP hydrolysis of Rabs can be enhanced by a GTPase-activating protein (GAP) leading to Rab inactivation. REPs carry only the GDP-bound form of Rab, and Rab effectors, proteins with which Rab interacts and through which it …
Rab GEFs and GAPs - PMC - PubMed Central (PMC)
Rabs are GTP-binding proteins with conserved functions in membrane trafficking. They are regulated by a diverse group of structurally unrelated GDP-GTP exchange factors (GEFs), and a family of GTP-hydrolysis activating proteins (GAPs) containing the conserved TBC domain.
