FIGURE 7. Model of YAP regulation.
The transcriptional activity of YAP may be induced by NRG1- and proteolysis-mediated activation of ERBB4 signaling. Other pathways, such as G protein-mediated signaling and EGF-induced stimulation of another ERBB family member, may indirectly activate YAP by inhibiting the Hippo kinase LATS1.
