Histone H3 is one of four histones that form a core octameric structure that is required for the packaging of DNA into nucleosomes, the most basic level of chromatin arrangement. Histones undergo a number of post-translational modifications (PTM) at their N- and C-terminal tails which can alter chromatin structure and stability, and influence DNA repair and gene expression. Histone H3 undergoes methylation of its lysine and arginine residues, with varying biological outcomes. The lysine 36 residue undergoes mono-, di-, or trimethylation which may be performed by one of many methyltransferase enzymes (SET2, NSD1, NSD2, NSD3, ASH1, SMYD2, SETMAR, KMT3A, and SETD3). Several studies have indicated that methylated lysine 36 residues promote Rpd3S-mediated deacetylation of other histones resulting in gene activation.，官网链接：https://www.sigmaaldrich.cn/product/mm/abe244s 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
