The intercellular Adherens Junctions (AJs) are specialized sub-apical structures that function as principle mediators of cell-cell adhesion. Their disassembly correlates with a loss of cell-cell contact and an acquisition of migratory potential. The Adherens Junctions have a crucial role both as sensors of extracellular stimuli and in regulating the dynamics of epithelial cell sheets or with neighboring cells. Cadherins, the Type-I transmembrane proteins of the Adherens Junctions, are principally responsible for homotypic c...
