ADP-ribosylation factor GTPase-activating protein 2 (Arfgap2)

GTPase-activating protein (GAP) for ADP ribosylation factor 1 (ARF1). May regulate coatomer-mediated protein transport from the Golgi complex to the endoplasmic reticulum.

Hydrolysis of ARF1-bound GTP may lead to dissociation of coatomer from Golgi- derived membranes to allow fusion with target membranes (By similarity). .
