γ-Catenin Mouse, Unlabeled, Clone: 15, BD

γ-Catenin (plakoglobin) was identified as a compenent of desmosomes where it associates with desmoglein. γ-Catenin and β-Catenin are closely related proteins that have significant homology with the Drosophila armadillo protein. In addition to complexing with E-Cadherin, γ-Catenin and β-Catenin have been observed in association with the intracellular domain of N-Cadherin. It has been proposed that one molecule of α-Catenin and at least one molecule of β-Catenin and γ-Catenin simultaneously bind to a single cadherin molecule. A 19 amino acid sequence of desmoglein (Dsg1) was found to be critical for binding of γ-Catenin. This region has significant homology to the catenin-binding domain of classical cadherins, thus suggesting a common mechanism for γ-Catenin localization at both adherens junctions and desmosomes.
