WebFeb 15, 2011 · Allfrey et al.1first reported histone acetylation in 1964. Since then, it has been shown that the acetylation of lysines is highly dynamic and regulated by the opposing action of two families of enzymes, histone acetyltransferases (HATs) and histone deacetylases (HDACs; for review, see reference 3). WebDec 11, 2009 · Here, we analyzed the effects of light on four histone modifications (acetylation and trimethylation of lysines 9 and 27 on histone H3: H3K9ac, H3K9me3, H3K27ac, and H3K27me3, respectively). Our genome-wide profiling of H3K9ac and H3K27ac revealed that these modifications are nontransposable element gene-specific.
