Preferred Label : Hippo Signaling Pathway;
NCIt synonyms : Salvador-Warts-Hippo Pathway; Hippo Pathway;
NCIt definition : A signaling pathway that controls organ size through the regulation of cell proliferation
and apoptosis. This pathway plays a role in progenitor cell self-renewal and expansion,
and dysregulation may play a role in tumorigenesis.;
Alternative definition : KEGG: Hippo signaling is an evolutionarily conserved signaling pathway that controls
organ size from flies to humans. In humans and mice, the pathway consists of the MST1
and MST2 kinases, their cofactor Salvador and LATS1 and LATS2. In response to high
cell densities, activated LATS1/2 phosphorylates the transcriptional coactivators
YAP and TAZ, promoting its cytoplasmic localization, leading to cell apoptosis and
restricting organ size overgrowth. When the Hippo pathway is inactivated at low cell
density, YAP/TAZ translocates into the nucleus to bind to the transcription enhancer
factor (TEAD/TEF) family of transcriptional factors to promote cell growth and proliferation.
YAP/TAZ also interacts with other transcriptional factors or signaling molecules,
by which Hippo pathway-mediated processes are interconnected with those of other key
signaling cascades, such as those mediated by TGF-beta and Wnt growth factors.;
