Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0003717
UniProt IDQ92572
Primary gene name(s)AP3S1
Synonym gene name(s)CLAPS3
Protein nameAP-3 complex subunit sigma-1
Protein functionPart of the AP-3 complex, an adaptor-related complex which is not clathrin-associated. The complex is associated with the Golgi region as well as more peripheral structures. It facilitates the budding of vesicles from the Golgi membrane and may be directly involved in trafficking to lysosomes. 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 locationGolgi apparatus. Cytoplasmic vesicle membrane;
Peripheral membrane protein;
Cytoplasmic side. Note=Component of the coat surrounding the cytoplasmic face of coated vesicles located at the Golgi complex.
