General Information
Term AP-2 adaptor complex ID (Ontology) GO:0030122 (Gene Ontology)
Definition A heterotetrameric AP-type membrane coat adaptor complex that consists of alpha, beta2, mu2 and sigma2 subunits, and links clathrin to the membrane surface of a vesicle, and the cargo receptors during receptor/clathrin mediated endocytosis. Vesicles with AP-2-containing coats are normally found primarily near the plasma membrane, on endocytic vesicles. In at least humans, the AP-2 complex can be heterogeneric due to the existence of multiple subunit isoforms encoded by different alpha genes (alphaA and alphaC).[ PubMed:10611976 PubMed:21097499 PubMed:22022230 PubMed:24322426 ]
Also Known As "HA2" ; "HA2 clathrin adaptor"
