RAB3GAP2 ELISA kits are immunoassay tools for the measurement of the protein RAB3 GTPase activating non-catalytic protein subunit 2, which is encoded by the RAB3GAP2 gene in humans. Functionally, this protein is a regulatory subunit of the Rab3 GTPase-activating (Rab3GAP) complex composed of RAB3GAP1 and RAB3GAP2, which has GTPase-activating protein (GAP) activity towards various Rab3 subfamily members (RAB3A, RAB3B, RAB3C and RAB3D), RAB5A and RAB43, and guanine nucleotide exchange factor (GEF) activity towards RAB18. The canonical protein structure is reported to have an amino acid length of 1393 residues, a mass of 156 kDa, and is a member of the Rab3-GAP regulatory subunit protein family. It is known to be localized in the ER and cytoplasm and is ubiquitously expressed across many tissue types. As many as 2 protein isoforms have been reported. The RAB3GAP2 gene has been associated with the disease, Martsolf syndrome. Other alias names for this target include RAB3-GAP150, RAB3GAP150, SPG69, WARBM2, p150, and MARTS1.
