adjacent cells initiate the assembly of an adhesion complex by homophilic binding of their extracellular domains. β-Catenin binds to the cytoplasmic portion of E-cadherin and connects it, via α-catenin, to the actin cytoskeleton. The linkage of cadherin to the cytoskeleton by β- and α-catenins is essential both for establishing cell-cell contacts and organizing the cytoskeleton.
To study the morphological changes in Drosophila apoptotic cells in vivo, Kessler and Muller used embryos genetically deficient in Diap1, in which apoptosis is activated in virtually all cells [9]. They define, morphologically and molecularly, two separate steps in the apoptotic process, revealing a progressive destruction of the adherens junction and shining new light on the mechanism by which the adhesive complexes are destabilized. During early apop- tosis, Arm is cleaved and the amounts of E-cadherin at the cell surface greatly reduced, whereas α-catenin remains stable. α-Catenin is only affected in a second step, defined as late-stage apoptosis, when E-cadherin and Arm have disappeared completely.
