SET1A-Mediated Mono-Methylation at K342 Regulates YAP Activation by Blocking Its Nuclear Export and Promotes Tumorigenesis.

 

2018 Jul 9;34(1):103-118.e9. doi: 10.1016/j.ccell.2018.06.002. Epub 2018 Jun 28.

 

YAP, a key effector of Hippo pathway, is activated by its translocation from cytoplasm to nucleus to regulate gene expression and promote tumorigenesis. Although the mechanism by which YAP is suppressed in cytoplasm has been well-studied, how the activated YAP is sequestered in the nucleus remains unknown. Here, we demonstrate that YAP is a nucleocytoplasmic shuttling protein and its nuclear export is controlled by SET1A-mediated mono-methylation of YAP at K342, which disrupts the binding of YAP to CRM1. YAP mimetic methylation knockin mice are more susceptible to colorectal tumorigenesis. Clinically, YAP K342 methylation is reversely correlated with cancer survival. Collectively, our study identifies SET1A-mediated mono-methylation at K342 as an essential regulatory mechanism for regulating YAP activity and tumorigenesis.
