Popis: Endogenous retroviruses (ERVs) compose a significant portion of mammalian genomes; however, how ERVs are regulated is not well known. Here the authors performed a genome-wide sgRNA screen to identify Morc3 as a mediator of ERV silencing. They show Morc3 associates with the H3.3 chaperone Daxx, and that loss of Morc3 leads to reduced H3.3 at ERVs.
