Regulatory mechanisms of SETD5 expression and activity. (A) SETD5 in NCoR-HDAC complex on primed enhancers is ubiquitinated and degraded by APC/C. The degradation of SETD5 from NCoR-HDAC3 co-repressor complex allows H3K27 acetylation and transits enhancers from primed to active state. (B) miR-139-5p or miR-126-5p binds to the SETD5 gene 3’ untranslated region (UTR) to repress the expression of SETD5 leading to low expression levels of Sema3A.
