Rab3 GTPase-activating protein catalytic subunit (IPR026147)

Short name: Rab3-GAP_cat_su

Overlapping homologous superfamilies


Family relationships



Small G proteins of the Rab family are regulators of intracellular vesicle traffic. Their rate of GTP hydrolysis is enhanced by specific GTPase-activating proteins (GAPs) that switch G proteins to their inactive form [PMID: 10859313]. This entry represents the Rab3 GTPase-activating protein catalytic subunit. It may participate in neurodevelopmental processes such as proliferation, migration and differentiation before synapse formation, and non-synaptic vesicular release of neurotransmitters [PMID: 9030515, PMID: 9852129].
