CC -!- FUNCTION: Part of the AP-3 complex, an adaptor-related complex which is
CC not clathrin-associated. The complex is associated with the Golgi
CC region as well as more peripheral structures. It facilitates the
CC budding of vesicles from the Golgi membrane and may be directly
CC involved in trafficking to lysosomes. In concert with the BLOC-1
CC complex, AP-3 is required to target cargos into vesicles assembled at
CC cell bodies for delivery into neurites and nerve terminals.
CC {ECO:0000269|PubMed:21998198}.
CC -!- SUBUNIT: Adaptor protein complex 3 (AP-3) is a heterotetramer composed
CC of two large adaptins (delta-type subunit AP3D1 and beta-type subunit
CC AP3B1 or AP3B2), a medium adaptin (mu-type subunit AP3M1 or AP3M2) and
CC a small adaptin (sigma-type subunit APS1 or AP3S2) (By similarity). AP-
CC 3 associates with the BLOC-1 complex. Interacts with AGAP1.
CC {ECO:0000250, ECO:0000269|PubMed:12967569}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus. Cytoplasmic vesicle membrane
CC {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic
CC side {ECO:0000250}. Note=Component of the coat surrounding the
CC cytoplasmic face of coated vesicles located at the Golgi complex.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the adaptor complexes small subunit family.
CC {ECO:0000305}.
