The adherens junction: a mosaic of cadherin and nectin clusters bundled by actin filaments.

ABSTRACT: Cadherin and nectin are distinct transmembrane proteins of adherens junctions. Their ectodomains mediate adhesion, whereas their cytosolic regions couple the adhesive contact to the cytoskeleton. Both these proteins are essential for adherens junction formation and maintenance. However, some basic aspects of these proteins, such as their organization in adherence junctions, have remained open. Therefore, using super-resolution microscopy and live imaging, we focused on the subjunctional distribution of these proteins. We showed that cadherin and nectin in the junctions of A431 cells and human keratinocytes are located in separate clusters. The size of each cluster is independent of that of the adjacent clusters and can significantly fluctuate over time. Several nectin and cadherin clusters
