Crystal Structure of a Human Tcf-4 / beta-Catenin Complex
Contents |
Overview
The multifunctional protein beta-catenin is important for cell adhesion, because it binds cadherins, and the Wnt signal transduction pathway, where it interacts with the Adenomatous polyposis coli (APC) protein and TCF/Lef family transcription factors. Mutations in APC or in beta-catenin are estimated to trigger formation of over 90% of all colon cancers. In colonic epithelia, these mutations produce elevated levels of Tcf4-beta-catenin, which stimulates a transcriptional response that initiates polyp formation and eventually malignant growth. Thus, disruption of the Tcf4-beta-catenin interaction may be an attractive goal for therapeutic intervention. Here we describe the crystal structure of a human Tcf4-beta-catenin complex and compare it with recent structures of beta-catenin in complex with Xenopus Tcf3 (XTcf3) and mammalian E-cadherin. The structure reveals anticipated similarities with the closely related XTcf3 complex but unexpectedly lacks one component observed in the XTcf3 structure.
