Abstract

The dramatic cell shape changes and movements of embryonic development require robust but dynamic linkage between cell-cell adherens junctions and the force-generating actomyosin cytoskeleton. Schmidt et al. combine genetic analysis and high resolution imaging to define the mechanism of action and function of Drosophila Polychaetoid, homolog of mammalian ZO-1, and reveal new insights into the complex molecular architecture of adherens junctions.
