CTNNB1 (catenin (cadherin-associated protein), beta 1, 88kDa) is a gene that encodes catenin beta-1 protein (also known as beta-catenin). beta-catenin is part of a complex of proteins that form adherens junctions, which are important for the establishment and maintenance of epithelial cell layers by regulating cell growth and adhesion between adjacent cells (PMID: 17854762). Mutant beta-catenin has been implicated in the pathogenesis of several cancers including melanoma, colorectal cancer, hepatocelluar carcinoma, and ovarian cancer (PMID: 12781368).
