Immunogen: beta-Catenin synthetic peptide (coupled to KLH) corresponding to amino acid residues in the N-terminal region of human beta-Catenin. This human sequence is highly conserved in rat and mouse beta-Catenins.

beta-Catenin is a 92 kDa protein that binds to the cytoplasmic tail of E-Cadherin. The cadherins, transmembrane adhesion molecules, are found with catenins at adherens junctions. Deletions in the cytoplasmic domain of ECadherin eliminate catenin binding and result in a loss of cell adhesion. Tyrosine phosphorylation of beta-Catenin can regulate its interaction with critical components of adherens junctions. Both Fer and Fyn kinases phosphorylate tyrosine 142 in vitro. Overexpression of these kinases in epithelial cells disrupts interactions between alpha and beta-Catenins. The phosphorylation of tyrosine 142 may act as a switch from the transcriptional to the adhesive role of beta-Catenin. Src family kinases can also phosphorylate tyrosine 654 in the C terminal armadillo repeat of beta-Catenin. This phosphorylation regulates beta-Catenin binding to E cadherin. Thus, sitespecific tyrosine phosphorylation of beta-Catenin may regulate specific protein-protein interactions leading to changes in cell adhesion.
