Protein Information (annotations from UniProt)

Database IDHIV0003713
UniProt IDO00203
Primary gene name(s)AP3B1
Synonym gene name(s)ADTB3A
Protein nameAP-3 complex subunit beta-1
Protein functionSubunit of non-clathrin- and clathrin-associated adaptor protein complex 3, AP-3 that plays a role in protein sorting in the late-Golgi/trans-Golgi network, TGN and/or endosomes. The AP complexes mediate both the recruitment of clathrin to membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules. AP-3 appears to be involved in the sorting of a subset of transmembrane proteins targeted to lysosomes and lysosome-related organelles. In concert with the BLOC-1 complex, AP-3 is required to target cargos into vesicles assembled at cell bodies for delivery into neurites and nerve terminals.
Subcellular locationCytoplasmic vesicle, clathrin-coated vesicle membrane {ECO:0000250};
Peripheral membrane protein {ECO:0000250};
Cytoplasmic side {ECO:0000250}. Golgi apparatus {ECO:0000250}. Note=Component of the coat surrounding the cytoplasmic face of coated vesicles located at the Golgi complex. {ECO:0000250}.
