Function
[TEAD4_MOUSE] 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 specifically and non-cooperatively to the Sph and GT-IIC 'enhansons' (5'-GTGGAATGT-3') and activates transcription. Binds to the M-CAT motif (By similarity). Might play a role in the embryonic development of skeletal muscle. [VGLL1_MOUSE] May act as a specific coactivator for the mammalian TEFs (By similarity).
Publication Abstract from PubMed
The structure of the complex between the transcription cofactor Vgll1 and the transcription factor TEAD4, the mammalian equivalent of the Drosophila Vestigial and Scalloped, respectively, is determined in this study. Remarkably, Vgll1 interacts with TEAD in a manner similar to the transcription coactivators, as well as oncogenes YAP and TAZ, despite having a varied primary sequence. Vgll1-TEAD complex upregulates the expression of IGFBP-5, a proliferation-promoting gene, and facilitates anchorage-independent cell proliferation. The YAP/TAZ-TEAD complex also upregulates several other proliferation-promoting genes and also promotes anchorage-independent cell proliferation. Given its structural and functional similarity to YAP/TAZ, Vgll1 has the potential to promote cancer progression.
