CC   -!- FUNCTION: Component of the adapter complexes which link clathrin to
CC       receptors in coated vesicles. Clathrin-associated protein complexes are
CC       believed to interact with the cytoplasmic tails of membrane proteins,
CC       leading to their selection and concentration. AP47 is a subunit of the
CC       plasma membrane adapter.
CC   -!- SUBUNIT: Adaptor protein complex 1 (AP-1) is a heterotetramer composed
CC       of two large adaptins (gamma- and beta'-type subunits), a medium
CC       adaptin (mu-type subunit AP47) and a small adaptin (sigma-type subunit
CC       AP19).
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus. Cytoplasmic vesicle, clathrin-
CC       coated vesicle membrane; Peripheral membrane protein; Cytoplasmic side.
CC       Note=Component of the coat surrounding the cytoplasmic face of coated
CC       vesicles located at the Golgi complex.
CC   -!- PTM: Regulated by phosphorylation. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the adaptor complexes medium subunit family.
CC       {ECO:0000305}.
