== Function ==
[[http://www.uniprot.org/uniprot/CLH1_RAT CLH1_RAT]] 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.

== Publication Abstract from PubMed ==
The "WD40" domain is a widespread recognition module for linking partner proteins in intracellular networks of signaling and sorting. The clathrin amino-terminal domain, which directs incorporation of cargo into coated pits, is a beta-propeller closely related in structure to WD40 modules. The crystallographically determined structures of complexes of the clathrin-terminal domain with peptides derived from two different cargo adaptors, beta-arrestin 2 and the beta-subunit of the AP-3 complex, reveal strikingly similar peptide-in-groove interactions. The two peptides in our structures contain related, five-residue motifs, which form the core of their contact with clathrin. A number of other proteins involved in endocytosis have similar "clathrin-box" motifs, and it therefore is likely that they all bind the terminal domain in the same way. We propose that a peptide-in-groove interaction is an important general mode by which beta-propellers recognize specific target proteins.

Peptide-in-groove interactions link target proteins to the beta-propeller of clathrin.,ter Haar E, Harrison SC, Kirchhausen T Proc Natl Acad Sci U S A. 2000 Feb 1;97(3):1096-100. PMID:10655490<ref>PMID:10655490</ref>
