CC   -!- FUNCTION: Subunit of clathrin-associated adaptor protein complex 1 that
CC       plays a role in protein sorting in the trans-Golgi network (TGN) and
CC       endosomes. The AP complexes mediate the recruitment of clathrin to
CC       membranes and the recognition of sorting signals within the cytosolic
CC       tails of transmembrane cargo molecules. Also involved in early steps of
CC       phagocytosis and macropinocytosis.
CC   -!- SUBUNIT: Adaptor protein complex 1 (AP-1) is a heterotetramer composed
CC       of two large adaptins (gamma-type subunit and beta-type subunit), a
CC       medium adaptin (mu-type subunit) and a small adaptin (sigma-type
CC       subunit). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus, trans-Golgi network. Cytoplasmic
CC       vesicle, clathrin-coated vesicle membrane {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the adaptor complexes small subunit family.
CC       {ECO:0000305}.
