The Hippo pathway is crucial in organ size control and its dysregulation contributes to tumorigenesis. Core components of the Hippo pathway include the protein kinases of MST1/2, MAP4Ks, and LATS1/2 as well as the transcription co‐activators of YAP/TAZ and their DNA binding partners TEADs. The current paradigm for regulation of this pathway centers on phosphorylation‐dependent nuclear‐cytoplasmic shuttling of YAP/TAZ through a complex network of upstream components that act via the LATS1/2 kinases. We have found that the Hippo pathway is also regulated by cellular metabolism and energy status. There is a functional crosstalk between Hippo and mTOR pathways as YAP/TAZ induces expression of amino acid transporter to promote mTOR activity. YAP/TAZ activity is potently regulated by mechanical signals, such as matrix stiffness. We will discuss new mechanistic insights how the Hippo pathway is regulated by mechano signals.
