Cadherin adhesion receptors are critical components for the maintenance of tissue architecture and organisation during development and in post-embryonic life. These receptors influence the actin cytoskeletal network by controlling its assembly at the junctions. Likewise, the actin cytoskeleton is required for cadherin integrity at cell-cell contacts. The junctional cytoskeleton is intrinsically dynamic and undergoes constant assembly and reorganisation to maintain a morphologically stable structure. This is governed by a host of molecular players that regulate actin assembly during nucleation and at post-nucleation stages. This review highlights the molecular machinery implicated in actin organisation at various stages of junctional assembly and its functional impact in simple epithelia and other model systems.
