ETFR-2/TEAD-4 Protein, Mouse (His)

ETFR-2/TEAD-4, a pivotal transcription factor, assumes a critical role in the Hippo signaling pathway, a pathway intricately linked to organ size control and tumor suppression through the regulation of proliferation and apoptosis. This pathway involves 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. Subsequently, MOB1 phosphorylates and inactivates the YAP1 oncoprotein and WWTR1/TAZ. ETFR-2/TEAD-4 acts by mediating the gene expression of YAP1 and WWTR1/TAZ, thus regulating crucial cellular processes such as proliferation, migration, and epithelial-mesenchymal transition (EMT) induction. The protein binds specifically and non-cooperatively to the Sph and GT-IIC 'enhansons' (5'-GTGGAATGT-3') and activates transcription. Additionally, it interacts with the M-CAT motif. While potentially playing a role in the embryonic development of skeletal muscle, ETFR-2/TEAD-4 also interacts with WWTR1/TAZ and YAP1, highlighting its multifaceted involvement in regulatory networks.
