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 the vacuole. Required for the transport via
CC the ALP pathway, which directs the transport of the cargo proteins PHO8
CC and VAM3 to the vacuole. {ECO:0000269|PubMed:10559961,
CC ECO:0000269|PubMed:9250663, ECO:0000269|PubMed:9335339}.
CC -!- SUBUNIT: Adaptor protein complex 3 (AP-3) is a heterotetramer composed
CC of 2 large adaptins (APL5 and APL6), a medium adaptin (APM3) and a
CC small adaptin (APS3). {ECO:0000269|PubMed:9250663,
CC ECO:0000269|PubMed:9335339}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus {ECO:0000269|PubMed:14562095}.
CC Cytoplasmic vesicle membrane {ECO:0000269|PubMed:10559961}; Peripheral
CC membrane protein {ECO:0000305|PubMed:10559961}; Cytoplasmic side
CC {ECO:0000305|PubMed:10559961}. Note=Component of the coat surrounding
CC the cytoplasmic face of coated vesicles located at the Golgi complex.
CC {ECO:0000269|PubMed:10559961, ECO:0000305}.
CC -!- MISCELLANEOUS: Present with 1240 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the adaptor complexes small subunit family.
CC {ECO:0000305}.
