Results show that Crb redistributes to the subapical region during pupal wing development and is not required for apical/basal and planar polarities of the pupal wing epithelium, but participates in prehair formation and hexagonal packing during morphogenesis. Crb is required during wing morphogenesis for the integrity and stability of adherens junctions and circumferential actomyosin belt. | Crumbs, Moesin and Yurt regulate junctional stability and dynamics for a proper morphogenesis of the Drosophila pupal wing epithelium.

Consistent with the role of Crb in apical membrane growth, RNAi-mediated knockdown of Crb results in decreased apical surface growth of tracheal cells and impaired axial elongation of the dorsal trunk. We conclude that Apn is a novel regulator of tracheal tube expansion in larval tracheae, the function of which is mediated by Crb. | The apical protein Apnoia interacts with Crumbs to regulate tracheal growth and inflation.
