Research Abstract

The genome of the eukaryote is packaged into chromatin, which permits dynamic and broad-ranging changes related to many important biological phenomena. Diverse posttranslational modifications of the core histones occur, often on the tail domains and related to transcriptional regulation. In this project we identified that histone H2A ubiquitylation inhibits histone H3K4 methylation resulting in transcriptional repression. Thus we clarified the role of histone modification and chromatin structure, which related to transcriptional regulation.
