Extended ncRNAs Interfere with Promoter Nucleosome Dynamics

Trends Genet. 2020 Sep;36(9):637-639. doi: 10.1016/j.tig.2020.05.011. Epub 2020 Jun 13.

Abstract

Eukaryotic genomes generate vast numbers of non-protein-coding RNAs (ncRNAs) that can inhibit mRNA synthesis through transcription interference, but the mechanisms are unclear. Gill et al. show that transcription of antisense ncRNAs induces 'elongation marks' on histones in promoter regions. These inhibit active nucleosome positioning required to maintain open transcription-initiation sites.

Keywords: antisense transcript; chromatin; nuclear surveillance; transcription.
