Research Abstract

In eukaryotes, heterochromatin mediates diverse biological processes including gene silencing and regulation of long-range chromatin interaction. However, the mechanism underlying heterochromatin formation is poorly understood. Our study showed that non-cording RNA in mammals involved in heterochromatin formation and the subunit of highly conserved RNA polymerase II was ubiquitinated by Cul4 ubiquitin ligase.
