Technical Data
AP2S1 (Adaptor-related Protein Complex 2 sigma 1 Subunit, AP2 Complex Subunit sigma 1, AP-2 Complex Subunit sigma 1, AP 17, AP17, AP17 delta, Clathrin Assembly Protein 2 Small Chain, Clathrin-associated/assembly/adaptor Protein Small 2, CLAPS2, Clathrin C
Adapter-related protein complex 2 sigma-1 subunit (AP2S1, AP17) is the component of the adaptor complexes which links clathrin to receptors in coated vesicles.It is the smallest polypeptide chain component of AP-2, a heterotetramer composed of two large adaptins (alpha-type subunit, AP2 alpha, and beta-type subunit, AP2 beta), a medium adaptin (mu-type subunit, AP2 mu1) and a small adaptin (sigma-type subunit, AP2S1).AP-2 is one of two major clathrin-associated protein complexes that interact with the cytoplasmic tails of membrane proteins, leading to their selection and concentration (1, 2).
