Members of this family adopt a structure consisting of a 5 stranded beta-sheet, flanked by one alpha helix on the outer side, and by two alpha helices on the inner side. This domain is required for binding to clathrin, and its subsequent polymerisation. Furthermore, a hydrophobic patch present in the domain also binds to a subset of D-phi-F/W motif-containing proteins that are bound by the alpha-adaptin appendage domain (epsin, AP180, eps15) [1].

Alpha adaptin is a heterotetramer which regulates clathrin-bud formation. The carboxyl-terminal appendage of the alpha subunit regulates translocation of endocytic accessory proteins to the bud site. This ig-fold domain is found in alpha, beta and gamma adaptins.	Domain
