| Ctnnbip1Gene Symbol: Ctnnbip1 Description: catenin, beta-interacting protein 1 Alias: beta-catenin-interacting protein 1 Species: rat Satoh K, Kasai M, Ishidao T, Tago K, Ohwada S, Hasegawa Y, et al. Anteriorization of neural fate by inhibitor of beta-catenin and T cell factor (ICAT), a negative regulator of Wnt signaling. Proc Natl Acad Sci U S A. 2004;101:8017-21 pubmed ..These results suggest that ICAT plays an important role in the anteriorization of neural cells by inhibiting the posteriorizing activity of Wnt signaling. .. Quasnichka H, Slater S, Beeching C, Boehm M, Sala Newby G, George S. Regulation of smooth muscle cell proliferation by beta-catenin/T-cell factor signaling involves modulation of cyclin D1 and p21 expression. Circ Res. 2006;99:1329-37 pubmed ..We therefore suggest that the N-cadherin and beta-catenin/TCF signaling pathway is a key modulator of VSMC proliferation via regulation of these 2 beta-catenin/TCF responsive genes. .. Guo M, Breslin J, Wu M, Gottardi C, Yuan S. VE-cadherin and beta-catenin binding dynamics during histamine-induced endothelial hyperpermeability. Am J Physiol Cell Physiol. 2008;294:C977-84 pubmed publisher ..Taken together, these data suggest that inflammatory agents like histamine cause a transient and reversible disruption of binding between beta-catenin and VE-cadherin, during which endothelial permeability is elevated. .. Kim Y, Kim J, Bae Y, Suh K, Jung J. ICAT participates in proliferation and osteogenic differentiation of human adipose tissue-derived mesenchymal stem cell. Life Sci. 2008;83:851-8 pubmed publisher ..Taken together, these findings indicated that ICAT participated in regulating hASC proliferation and differentiation by modulating Wnt signaling. .. Daniels D, Weis W. ICAT inhibits beta-catenin binding to Tcf/Lef-family transcription factors and the general coactivator p300 using independent structural modules. Mol Cell. 2002;10:573-84 pubmed ..The C-terminal armadillo repeats of beta-catenin may be an attractive target for compounds designed to disrupt aberrant beta-catenin-mediated transcription associated with various cancers. .. Graham T, Clements W, Kimelman D, Xu W. The crystal structure of the beta-catenin/ICAT complex reveals the inhibitory mechanism of ICAT. Mol Cell. 2002;10:563-71 pubmed ..Thus, it should be possible to design cancer therapeutics that inhibit beta-catenin-mediated transcriptional activation without interfering with cell adhesion. .. Kanamori M, Sandy P, Marzinotto S, Benetti R, Kai C, Hayashizaki Y, et al. The PDZ protein tax-interacting protein-1 inhibits beta-catenin transcriptional activity and growth of colorectal cancer cells. J Biol Chem. 2003;278:38758-64 pubmed ..These data suggest that TIP-1 may represent a novel regulatory element in the Wnt/beta-catenin signaling pathway. .. Penman G, Leung L, Nathke I. The adenomatous polyposis coli protein (APC) exists in two distinct soluble complexes with different functions. J Cell Sci. 2005;118:4741-50 pubmed Tago K, Nakamura T, Nishita M, Hyodo J, Nagai S, Murata Y, et al. Inhibition of Wnt signaling by ICAT, a novel beta-catenin-interacting protein. Genes Dev. 2000;14:1741-9 pubmed ..These results suggest that ICAT negatively regulates Wnt signaling via inhibition of the interaction between beta-catenin and TCF and is integral in development and cell proliferation. ..
