Function

[YAP1_HUMAN] Transcriptional regulator which can act both as a coactivator and a corepressor and is the critical 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. 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. Plays a key role to control cell proliferation in response to cell contact. Phosphorylation of YAP1 by LATS1/2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration. The presence of TEAD transcription factors are required for it to stimulate gene expression, cell growth, anchorage-independent growth, and epithelial mesenchymal transition (EMT) induction. Isoform 2 and isoform 3 can activate the C-terminal fragment (CTF) of ERBB4 (isoform 3).^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

The single mutation L30 K in the Hu-Yap65 WW domain increased the stability of the complex with the peptide GTPPPPYTVG (K(d)=40(+/-5) microM). Here we report the refined solution structure of this complex by NMR spectroscopy and further derived structure-activity relationships by using ligand peptide libraries with truncated sequences and a substitution analysis that yielded acetyl-PPPPY as the smallest high-affinity binding peptide (K(d)=60 microM). The structures of two new complexes with weaker binding ligands chosen based on these results (N-(n-octyl)-GPPPYNH(2) and Ac-PLPPY) comprising the wild-type WW domain of Hu-Yap65 were determined. Comparison of the structures of the three complexes were useful for identifying the molecular basis of high-affinity: hydrophobic and specific interactions between the side-chains of Y28 and W39 and P5' and P4', respectively, and hydrogen bonds between T37 (donnor) and P5' (acceptor) and between W39 (donnor) and T2' (acceptor) stabilize the complex.The structure of the complex L30 K Hu-Yap65 WW domain/GTPPPPYTVG is compared to the published crystal structure of the dystrophin WW domain bound to a segment of the beta-dystroglycan protein and to the solution structure of the first Nedd4 WW domain and its prolin-rich ligand, suggesting that WW sequences bind proline-rich peptides in an evolutionary conserved fashion. The position equivalent to T22 in the Hu-Yap65 WW domain sequence is seen as responsible for differentiation in the binding mode among the WW domains of group I.

Solution structures of the YAP65 WW domain and the variant L30 K in complex with the peptides GTPPPPYTVG, N-(n-octyl)-GPPPY and PLPPY and the application of peptide libraries reveal a minimal binding epitope.,Pires JR, Taha-Nejad F, Toepert F, Ast T, Hoffmuller U, Schneider-Mergener J, Kuhne R, Macias MJ, Oschkinat H J Mol Biol. 2001 Dec 14;314(5):1147-56.
