AP-1 complex subunit sigma-2 is a protein that in humans is encoded by the AP1S2 gene.Adaptor protein complex 1 is found at the cytoplasmic face of coated vesicles located at the Golgi complex where it mediates both the recruitment of clathrin to the membrane and the recognition of sorting signals within the cytosolic tails of transmembrane receptors. This complex is a heterotetramer composed of two large one medium and one small adaptin subunit.
