CLATHRIN TERMINAL DOMAIN COMPLEXED WITH TLPWDLWTT
Overview
During the assembly of clathrin-coated vesicles, many peripheral membrane, proteins, including the amphiphysins, use LLDLD-type clathrin-box motifs, to interact with the N-terminal beta-propeller domain (TD) of clathrin., The 2.3 A-resolution structure of the clathrin TD in complex with a, TLPWDLWTT peptide from amphiphysin 1 delineates a second clathrin-binding, motif, PWXXW (the W box), that binds at a site on the TD remote from the, clathrin box-binding site. The presence of both sequence motifs within the, unstructured region of the amphiphysins allows them to bind more tightly, to free TDs than do other endocytic proteins that contain only, clathrin-box motifs. This property, along with the propensity of the, N-terminal BAR domain to bind curved membranes, will preferentially, localize amphiphysin and its partner, dynamin, to the periphery of, invaginated clathrin lattices.
