The catenins are polypeptides that bind to the conserved cytoplasmic tail of cadherins and are required for cadherin function. a-Catenin is a 102kD protein that is associated with the cadherin indirectly through its interaction with b-catenin and g-catenin. b-Catenin and its homolog plakoglobin associate directly with the cadherin. Thus, the cell-cell adherens junction is a structure composed of the transmembrane cadherin, which is associated directly with either b-catenin or plakoglobin, which in turn assoctiates directly with a-catenin. a-Catenin then mediates the interaction between the cadherin-catenin complex and the actin cytoskeleton (5,6). a-Catenin has been characterized as a tumor suppressor, suggesting that it may have a regulatory function in regulation to its structural role.
