H3 Lysine 4 Is Acetylated at Active Gene Promoters and Is Regulated by H3 Lysine 4 Methylation

Methylation of histone H3 lysine 4 (H3K4me) is an evolutionarily conserved modification whose role in the regulation of gene expression has been extensively studied组蛋白H3赖氨酸4甲基化（H3K4me）是一种进化保守的修饰类型，其在基因表达调控中的作用已被广泛研究。
