|PubMed Abstract||The Salvador-Warts-Hippo (SWH) pathway is a complex signaling network that controls both developmental and regenerative tissue growth. Using a genetic screen in Drosophila melanogaster, we identified the sterile 20-like kinase, Tao-1, as an SWH pathway member. Tao-1 controls various biological phenomena, including microtubule dynamics, animal behavior, and brain development. Here we describe a role for Tao-1 as a regulator of epithelial tissue growth that modulates activity of the core SWH pathway kinase cassette. Tao-1 functions together with Hippo to activate Warts-mediated repression of Yorkie. Tao-1's ability to control SWH pathway activity is evolutionarily conserved because human TAO1 can suppress activity of the Yorkie ortholog, YAP. Human TAO1 controls SWH pathway activity by phosphorylating, and activating, the Hippo ortholog, MST2. Given that SWH pathway activity is subverted in many human cancers, our findings identify human TAO kinases as potential tumor suppressor genes.|
