BETA2-ADAPTIN APPENDAGE DOMAIN, FROM CLATHRIN ADAPTOR AP2
OverviewOverview
The heterotetrameric AP2 adaptor (alpha, beta 2, mu 2 and sigma 2, subunits) plays a central role in clathrin-mediated endocytosis. We, present the protein recruitment function and 1.7 A resolution structure of, its beta 2-appendage domain to complement those previously determined for, the mu 2 subunit and alpha appendage. Using structure-directed, mutagenesis, we demonstrate the ability of the beta 2 appendage alone to, bind directly to clathrin and the accessory proteins AP180, epsin and, eps15 at the same site. Clathrin polymerization is promoted by binding of, clathrin simultaneously to the beta 2-appendage site and to a second site, on the adjacent beta 2 hinge. This results in the displacement of the, other ligands from the beta 2 appendage. Thus clathrin binding to an, ... [(full description)]
