RAB3 GTPase Activating Protein Subunit 2, or RAB3 GTPase activating non-catalytic protein subunit 2, is a human gene encoded by RAB3GAP2. It may also be known as: Rab3 GTPase-activating protein non-catalytic subunit; Rab3 GTPase-activating protein 150 kDa subunit; Rab3-GAP p150; Rab3-GAP150; Rab3-GAP regulatory subunit; RGAP-iso; RAB3 GTPase activating protein subunit 2 (non-catalytic); RAB3GAP150; SPG69; WARBM2. The encoded protein has an amino acid length of 1393 and a mass of 156.0 kDa. RAB3 GTPase Activating Protein Subunit 2 is a member of the Rab3-GAP regulatory subunit family. Homologs of this gene exist in other organisms, including: Zebrafish, Chicken.
