Protein Information (annotations from UniProt)

Database IDHIV0006620
UniProt IDQ9UL26
Primary gene name(s)RAB22A
Synonym gene name(s)RAB22
Protein nameRas-related protein Rab-22A
Protein functionPlays a role in endocytosis and intracellular protein transport. Mediates trafficking of TF from early endosomes to recycling endosomes. Required for NGF-mediated endocytosis of NTRK1, and subsequent neurite outgrowth. Binds GTP and GDP and has low GTPase activity. Alternates between a GTP-bound active form and a GDP-bound inactive form. {ECO:0000269|PubMed:16537905, ECO:0000269|PubMed:21849477}.
