How adhesive interactions between cells generate and maintain animal tissue structure remains one of the most challenging and long-standing questions in cell and developmental biology. Adherens junctions (AJs) and the cadherin-catenin complexes at their core are therefore the subjects of intense research. Recent work has greatly advanced our understanding of the molecular organization of AJs and how cadherin-catenin complexes engage actin, microtubules and the endocytic machinery. As a result, we have gained important insights into the molecular mechanisms of tissue morphogenesis.
