Protein Information (annotations from UniProt)

Database IDHIV0001147
UniProt IDP31150
Primary gene name(s)GDI1
Synonym gene name(s)GDIL, OPHN2, RABGDIA, XAP4
Protein nameRab GDP dissociation inhibitor alpha
Protein functionRegulates the GDP/GTP exchange reaction of most Rab proteins by inhibiting the dissociation of GDP from them, and the subsequent binding of GTP to them. Promotes the dissociation of GDP-bound Rab proteins from the membrane and inhibits their activation. Promotes the dissociation of RAB1A, RAB3A, RAB5A and RAB10 from membranes. {ECO:0000269|PubMed:23815289}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:19570034}. Golgi apparatus, trans-Golgi network {ECO:0000269|PubMed:19570034}.
