The Hippo pathway controls development and facilitates regenerative processes through regulating its transcriptional co‐activators YAP and TAZ, and can cause cancer if the pathway is not tightly regulated (Moroishi et al, 2015a; Fulford et al, 2018; Davis & Tapon, 2019; Rognoni & Walko, 2019; Salem & Hansen, 2019; Zanconato et al, 2019; Thompson, 2020). Here, YAP1 is linked to cancer.
