dc.description.abstractEmerging evidence suggests functional regulation of the Hippo pathway by the actin cytoskeleton, although the detailed molecular mechanism remains incomplete. In a genetic screen, we identified a requirement for -Spectrin in the posterior follicle cells for the oocyte repolarization process during Drosophila mid-oogenesis. -Spectrin mutations lead to loss of Hippo signaling activity in the follicle cells. A similar reduction of Hippo signaling activity was observed after -Spectrin knockdown in mammalian cells. We further demonstrated that -spectrin mutations disrupt the basal actin network in follicle cells. The abnormal stress fiber-like actin structure on the basal side of follicle cells provides a likely link between the -spectrin mutations and the loss of the Hippo signaling activity phenotype.en_US
