Clathrin terminal domain complexed with TLPWDLWTTClathrin terminal domain complexed with TLPWDLWTT
Structural highlights
Function[CLH1_BOVIN] Clathrin is the major protein of the polyhedral coat of coated pits and vesicles. Two different adapter protein complexes link the clathrin lattice either to the plasma membrane or to the trans-Golgi network. [AMPH_HUMAN] May participate in mechanisms of regulated exocytosis in synapses and certain endocrine cell types. May control the properties of the membrane associated cytoskeleton.

Publication Abstract from PubMedDuring 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. Two distinct interaction motifs in amphiphysin bind two independent sites on the clathrin terminal domain beta-propeller.,Miele AE, Watson PJ, Evans PR, Traub LM, Owen DJ Nat Struct Mol Biol. 2004 Mar;11(3):242-8.
