Comments
  • FUNCTION: Subunit of clathrin-associated adaptor protein complex 1 that plays a role in protein sorting in the late-Golgi/trans-Golgi network (TGN) and/or endosomes. The AP complexes mediate both the recruitment of clathrin to membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules.
  • SUBUNIT: Adaptor protein complex 1 (AP-1) is an heterotetramer composed of two large adaptins (gamma-type subunit AP1G1 and beta-type subunit AP1B1), a medium adaptin (mu-type subunit AP1M1 or AP1M2) and a small adaptin (sigma-type subunit AP1S1 or AP1S2 or AP1S3).
  • SUBCELLULAR LOCATION: Golgi apparatus. Cytoplasmic vesicle, clathrin-coated vesicle membrane; Peripheral membrane protein; Cytoplasmic side. Note=Component of the coat surrounding the cytoplasmic face of coated vesicles located at the Golgi complex.
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing.
    NameA
    Isoform IDP52303-1
    This is the isoform sequence displayed in this entry.
    NameB
    Isoform IDP52303-2
    Features which should be applied to build the isoform sequence: VSP_000164.
  • PTM: The N-terminus is blocked.
  • SIMILARITY: Belongs to the adaptor complexes large subunit family.
  • CAUTION: Was originally (PubMed:2495531) thought to be part of the complex AP-2.
