The caspase 3-mediated proteolytic processing of full-length Dsg2, the most widespread desmosomal cadherin, results in disappearance of Dsg2 from the cell surface and appearance of a 70-kDa fragment in the cytosol. Loss of Dsg2 from the cell surface may contribute to the progressive loss of intercellular adhesion strength during apoptosis (Cirillo et al., 2008)
