Diagram comparing the major molecular constituents of the two intercellular adhesive junc- tions found m epithelial tissues. The adhesion molecules in both junctions are members of the larger cadherin family of calcium-dependent cell adhesion molecules. These are desmogleins and desmocollins in the desmosome (top), and classic cadherins, such as E-cadherin, in the adherens junction (bottom). Members of the armadillo gene family, plakoglobin and /
