General annotation (Comments)
| 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 RNP24. 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. |
| Subunit structure | Interacts with ARF1. Interacts with the COPI coat proteins, KDELR1 and RNP24. The interaction with RNP24 inhibits the GAP activity By similarity. |
| Subcellular location | Cytoplasm By similarity. Golgi apparatus By similarity. Note: Associates with the Golgi complex By similarity. |
| Domain | The region downstream of Arf-GAP domain is essential to GAP activity in vivo. This region may be required for its targeting to Golgi membranes By similarity. |
| Sequence similarities | Contains 1 Arf-GAP domain. |
| Sequence caution | The sequence CAB70901.1 differs from that shown. Reason: Miscellaneous discrepancy. Intron retention. |
