Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0011460
UniProt IDQ96PC3
Primary gene name(s)AP1S3
Synonym gene name(s)unknown
Protein nameAP-1 complex subunit sigma-3
Protein functionSubunit 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. Involved in TLR3 trafficking, PubMed:24791904. {ECO:0000269|PubMed:24791904}.
Subcellular locationGolgi apparatus. Cytoplasmic vesicle membrane;
Peripheral membrane protein;
Cytoplasmic side. Membrane, clathrin-coated pit. Note=Component of the coat surrounding the cytoplasmic face of coated vesicles located at the Golgi complex.
