- (RSS) (BioRxiv All) Histone succinylation directly inhibits Jumonji domain demethylases and stabilizes repressive chromatin states: Herein we uncover a relationship between histone succinylation and Jumonji (JmjC) domain-containing histone demethylases. We used quantitative proteomics and peptide pull-down assays to identify JmjC demethylases as candidate interactors with succinylated histone peptides. Succinyl-lysine peptides bind and inhibit the… https://www.biorxiv.org/content/10.64898/2026.05.29.728167v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
