The Crumbs3-Pals1 complex participates in the establishment of polarity in mammalian epithelial cells.


In Drosophila, the Crumbs-Stardust-Discs-lost complex is required during the establishment of polarized epithelia. Embryos that lack a component of this complex or overexpress Crumbs exhibit defects in epithelial morphogenesis. We recently cloned a novel mammalian epithelial Crumbs isoform, Crumbs3 (CRB3). CRB3 exists in a complex at tight junctions (TJs… (More)
