Current perspectives on cadherin-cytoskeleton interactions and dynamics

Abstract

Cells are linked together dynamically by adhesion molecules, such as the classical cadherins. E-cadherin, which mediates epithelial cell–cell interactions, plays fundamental roles in tissue organization and is often perturbed in diseases such as cancer. It has long been recognized that the biology of E-cadherin arises from cooperation between adhesion and the actin cytoskeleton. A major feature is the generation of contractile forces at junctions, yielding patterns of tension that contribute to tissue integrity and patterning. Here we discuss recent developments in understanding how cadherin junctions integrate signaling and cytoskeletal dynamics to sense and generate force.
