Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0003747
UniProt IDQ8N6H7
Primary gene name(s)ARFGAP2
Synonym gene name(s)ZNF289
Protein nameADP-ribosylation factor GTPase-activating protein 2
Protein functionGTPase-activating protein, GAP for ADP ribosylation factor 1, ARF1. Implicated in coatomer-mediated protein transport between the Golgi complex and the endoplasmic reticulum. Hydrolysis of ARF1-bound GTP may lead to dissociation of coatomer from Golgi-derived membranes to allow fusion with target membranes. {ECO:0000269|PubMed:17760859}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:17760859}. Golgi apparatus membrane {ECO:0000269|PubMed:17760859};
Peripheral membrane protein {ECO:0000269|PubMed:17760859};
Cytoplasmic side {ECO:0000269|PubMed:17760859}. Note=Also found on peripheral punctate structures likely to be endoplasmic reticulum-Golgi intermediate compartment.
