General Information
Term AP-1 adaptor complex ID (Ontology) GO:0030121 (Gene Ontology)
Definition A heterotetrameric AP-type membrane coat adaptor complex that consists of beta1, gamma, mu1 and sigma1 subunits and links clathrin to the membrane surface of a vesicle; vesicles with AP-1-containing coats are normally found primarily in the trans-Golgi network. In at least humans, the AP-1 complex can be heterogeneric due to the existence of multiple subunit isoforms encoded by different genes (gamma1 and gamma2, mu1A and mu1B, and sigma1A, sigma1B and sigma1C).[ PubMed:10611976 PubMed:21097499 ]
Also Known As "HA1" ; "HA1 clathrin adaptor"
