WebGenerally, arginine methylation is involved in gene activation and histone methyltransferases (HMTs) are recruited to promoters as coactivators. By comparison, lysine methylation can have multiple effects on chromatin function, depending on the specific lysine residue and the level of modification (mono-, di-, or trimethylation of a single lysine). Web18 iun. 2024 · Author summary Histone modifications, the specific chemical modifications on histone proteins, are key for regulating the packing of DNA, and thus have important influence on diverse biological processes.

The diverse functions of histone lysine methylation - Nature

WebLysine methylation has been implicated in both transcriptional activation (H3K4, K36, K79) and silencing (H3K9, K27, H4K20). The degree of methylation is associated with different outcomes. For example, H4K20 monomethyation (H4K20me1) is observed in the bodies of active genes, while H4K20 trimethylation (H4K20me3) is affiliated with gene ... WebThe chromo domain protein like heterochromatin protein1 (LHP1) is a subunit of a plant PRC1-like complex in Arabidopsis thaliana and recognizes histone H3 lysine 27 trimethylation, a silencing epigenetic mark deposited by the PRC2 complex.
