Fig. 7: Working model of RNF214 functions in HCC.

YAP and TAZ are transcription co-activators that activate transcriptional activities of TEADs to promote HCC tumorigenesis. RNF214 induces TEADs non-proteolytic ubiquitylation at a single conserved lysine site, enhances the interactions between TEADs and YAP, and then promotes transactivation of the downstream genes, thereby leading to enhanced tumor progression.
