Monoclonal Mouse Affinity Purified B IP IH IC IF
Catenins are proteins that connect cadherin/beta-catenin cell adhesion complexes to the actin cytoskeleton. Although originally discovered in testis, alpha-T-catenin is expressed in other tissues, the highest levels being observed in the heart. Immunohistochemical analysis showed human alpha-T-catenin localization at intercalated discs of cardiomyocytes and in peritubular myoid cells of testis. It is proven that alpha-T-catenin can functionally restore cell-cell adhesion in colon cancer cells lacking alpha-catenins. This indicates that this protein is involved in the formation of specific cell-cell contacts in specific types of muscle cells.
The encoded protein has about the same predicted size (100kD) as other alpha-catenins to which it shows an overall amino acid identity of 57%. In cells transfected with alpha-T-catenin cDNA, interaction with beta-catenin was demonstrated by co-immunoprecipitation.
