|Function||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 thus, is required for the dissociation of coat proteins from Golgi-derived membranes and vesicles, a prerequisite for vesicle's fusion with target compartment. Probably regulates ARF1-mediated transport via its interaction with the KDELR proteins and TMED2. Overexpression induces the redistribution of the entire Golgi complex to the endoplasmic reticulum, as when ARF1 is deactivated. Its activity is stimulated by phosphoinosides and inhibited by phosphatidylcholine (By similarity).|
|Cellular Location||Cytoplasm. Golgi apparatus. Note=Associates with the Golgi complex|

The protein encoded by this gene is a GTPase-activatingprotein (GAP) which associates with the Golgi apparatus and whichinteracts with ADP-ribosylation factor 1 (ARF1). The encodedprotein promotes hydrolysis of ARF1-bound GTP and is required forthe dissociation of coat proteins from Golgi-derived membranes andvesicles. Dissociation of the coat proteins is required for thefusion of these vesicles with target compartments. The activity ofthis protein is stimulated by phosphoinosides and inhibited byphosphatidylcholine. Two transcript variants encoding differentisoforms have been found for this gene.
