<unk>  is an epigenetic modification to the DNA packaging protein Histone H3. It is a mark that indicates the acetylation at the 14th lysine residue of the histone H3 protein.<unk>  has not been widely studied partly due to previous lack of commercially available antibody. H3K9ac and<unk>  have been shown to be part of the active promoter state. They are also present over bivalent promoters and active enhancers.<unk>  is also enriched over a subset of inactive promoters. The Tudor domain of the H3K9 methyltransferase SETDB1 binds to methylated H3 with both K14 acetylation and K9 methylation. SETDB1 silences retroviruses and gene regulation.
