Synthetic peptide corresponding to residues around Ser37 of human beta-catenin. Species sequence homology: porcine and zebrafish
Beta-catenin is one of the key downstream effectors in the Wnt signaling pathway (1). It has been implicated in two major biological processes of vertebrates: early embryonic development (2) and tumorigenesis (3). GSK-3 beta or other kinases may destabilize beta-catenin by phosphorylating it at serines 33, 37, 45 and threonine 41 (4). Stabilizing mutations of these phosphorylation sites in beta-catenin have been found in many tumor cell lines (5).
