機能

Transcriptional coactivator which acts as a downstream regulatory target in the Hippo signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis (PubMed : 11118213, PubMed : 18227151, PubMed : 23911299). The core of this pathway is composed of a kinase cascade wherein STK3/MST2 and STK4/MST1, 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 (PubMed : 18227151). WWTR1 enhances PAX8 and NKX2-1/TTF1-dependent gene activation (PubMed : 19010321). In conjunction with YAP1, involved in the regulation of TGFB1-dependent SMAD2 and SMAD3 nuclear accumulation (PubMed : 18568018). Plays a key role in coupling SMADs to the transcriptional machinery such as the mediator complex (PubMed : 18568018). Regulates embryonic stem-cell self-renewal, promotes cell proliferation and epithelial-mesenchymal transition (PubMed : 18227151, PubMed : 18568018).

翻訳後修飾

Phosphorylated by LATS2 and STK3/MST2. Phosphorylation by LATS2 results in creation of 14-3-3 binding sites, retention in the cytoplasm, and functional inactivation. Phosphorylation results in the inhibition of transcriptional coactivation through YWHAZ-mediated nuclear export. Phosphorylated in the nucleus by PRP4K; phosphorylation leads to nuclear exclusion (PubMed:29695716).. Ubiquitinated at Lys-46; leading to proteasomal degradation. Deubiquitinated and stabilized by UCHL1 at Lys-46; leading to inhibition of osteoclastogenesis.
