Transcription factor which plays a key role in the Hippo signaling pathway, a pathway involved in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein MST1/MST2, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Acts by mediating gene expression of YAP1 and WWTR1/TAZ, thereby regulating cell proliferation, migration and epithelial mesenchymal transition (EMT) induction. Binds to multiple functional elements of the human chorionic somatomammotropin-B gene enhancer. Note: This description may include information from UniProtKB.
Molecular Function: protein binding; sequence-specific DNA binding; transcription factor activity
Biological Process: asymmetric neuroblast division; embryonic organ development; female pregnancy; positive regulation of transcription from RNA polymerase II promoter; regulation of transcription from RNA polymerase II promoter; transcription initiation from RNA polymerase II promoter
