label: AP-1 adaptor complex binding
label_lc: ap-1 adaptor complex binding
description: "Binding to an AP-1 adaptor complex. The AP-1 adaptor complex is 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. 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)."
