WebHistone modifications act in diverse biological processes such as transcriptional activation/inactivation, chromosome packaging, and DNA damage/repair. In most species, histone H3 is primarily acetylated at lysines 9, 14, 18, 23, and 56, methylated at arginine 2 and lysines 4, 9, 27, 36, and 79, and phosphorylated at ser10, ser28, Thr3, and Thr11. Web1 de jun. de 2012 · Histone modifications could be re-established by complexes that recognize a specific modification on an inherited parental histone and catalyze the same type of modification on adjacent, newly deposited nucleosomes. For example, H3K27me3 might recruit PRC2 to maintain the mark through replication [107, 108].
