abstract：:beta-Catenin was initially characterized as a protein interacting with the cadherin cytoplasmic tail and regulating cell-cell contacts and actin cytoskeleton interactions. Moreover, the gene coding for the Drosophila orthologue of beta-catenin, armadillo, was independently identified downstream of wingless in the segm...
