ADP-ribosylation factor GTPase-activating protein 1 (ARFGAP1)

GTPase-activating protein (GAP) for the ADP ribosylation factor 1 (ARF1). Involved in membrane trafficking and /or vesicle transport.

Promotes hydrolysis of the ARF1-bound GTP and so, is required for the dissociation of coat proteins from Golgi-derived membranes and vesicles, a necessity for vesicle's combination with target compartment. Probably regulates ARF1-mediated transportation via its interaction with the KDELR proteins and TMED2.
