CC -!- FUNCTION: Component of the adaptor 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. AP50 is a subunit of the
CC plasma membrane adaptor. The complex binds polyphosphoinositide-
CC containing lipids. {ECO:0000250|UniProtKB:P84092,
CC ECO:0000250|UniProtKB:Q96CW1}.
CC -!- SUBUNIT: Adaptor protein complex 2 (AP-2) is a heterotetramer composed
CC of two large adaptins (alpha-type subunit and beta-type subunit), a
CC medium adaptin (mu-type subunit) and a small adaptin (sigma-type
CC subunit). {ECO:0000250|UniProtKB:Q96CW1}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q96CW1}.
CC Membrane, coated pit {ECO:0000250|UniProtKB:Q96CW1}; Peripheral
CC membrane protein {ECO:0000250|UniProtKB:Q96CW1}; Cytoplasmic side
CC {ECO:0000250|UniProtKB:Q96CW1}.
CC -!- SIMILARITY: Belongs to the adaptor complexes medium subunit family.
CC {ECO:0000305}.
