α-Catenin phosphorylation is tension-sensitive and supports epithelial barrier functions via afadin.
Zonula adherens junctions (zAJs) are spatially proximal to tight junctions (TJs), in a superstructure known as the apical junctional complex (AJC). A key component of the AJC is a circumferential ring of F-actin, but how actomyosin contractility drives AJC structure and epithelial barrier function is incompletely under...
