WebMay 6, 2024 · Histone H3K9 methylation is a critical marker for transcriptional silencing and heterochromatin formation, mostly constitutive heterochromatin formation. Methylation states at H3K9 can be mono- (H3K9me1), di- (H3K9me2), or tri- (H3K9me3) methylation. WebDec 17, 2014 · The histone tails are readily accessible to various enzymes, including histone methyltransferases (HMTs), histone acetyltransferases (HATs), histone deacetylases (HDACs), and kinases. The histone-modifying enzymes can add or remove covalent modifications and are called “writers” and “erasers,” respectively. port bolivar tx zip code
