H3K36me - Wikipedia
H3K36me is an epigenetic modification to the DNA packaging protein Histone H3, specifically, the mono-methylation at the 36th lysine residue of the histone H3 protein. There are diverse modifications at H3K36, such as phosphorylation, methylation, acetylation, and ubiquitylation, which have many important biological processes. [ 1 ]
Structural and functional specificity of H3K36 methylation
2022年5月18日 · The methylation of histone H3 at lysine 36 (H3K36me) is essential for maintaining genomic stability. Indeed, this methylation mark is essential for proper transcription, recombination, and DNA damage response. Loss- and gain-of-function mutations in H3K36 methyltransferases are closely linked to human developmental disorders and various cancers.
Nature专家点评丨路超团队等揭示H3K36甲基化修饰与DNA甲基化 …
本研究揭示DNMT3A优先选择H3K36二甲基化区域,促进基因间区的DNA甲基化,并且Sotos综合征病人的血样和NSD1突变肿瘤中都出现了基因间区DNA甲基化的选择性丢失。 这一工作对H3K36甲基化修饰和DNA甲基化修饰间的调控作用做出了新的拓展,并且这一机制在疾病发生过程中有着潜在的生物学意义。 原文链接:doi.org/10.1038/s41586- 制版人:珂.
Unique and Shared Roles for Histone H3K36 Methylation States in ...
2020年6月9日 · H3K36me limits co-transcriptional histone acetylation in two main ways: by recruitment and activation of the Rpd3S deacetylation complex that removes H3 and H4 N-terminal tail acetylation (e.g., H3K27ac); and by the ability of H3K36me to repel the histone exchange factor Asf1, which helps deposit the histone exchange-associated mark H3K56ac ...
PNAS | 路超团队等揭示组蛋白H3K36M突变促癌机制中的关键因素
在最新研究中,路超团队及合作者首先在小鼠细胞系中构建了H3K36M突变株、H3K36me2甲基转移酶 Nsd1 /2双敲除株以及H3K36me3甲基转移酶 Setd2 敲除株。 研究通过 ChIP-seq 发现H3K36M突变对基因组范围内H3K36me2和H3K36me3修饰的影响有显著差异:H3K36M突变会导致H3K36me2修饰在整体水平上大幅降低,而对H3K36me3修饰水平的影响较小。
