  1. ...distinct forms, which contribute to gene repression through different mechanisms. Facultative heterochromatin tends to silence genes in a developmental or cell type–specific manner (Kim and Kingston 2022). It is depleted in histone acetylation and is distinguished by enrichment of H3K27 trimethylation (H3K...
  2. ...by observations of H3K27me3 redistribution in response to defects in constitutive heterochromatin. More than a decade ago, Peters et al. (2003) noticed that mouse cells defective in both of the SUV39H methyltransferases, which are responsible for the trimethylation of histone H3 lysine 9 (H3K9me3) characteristic...
  3. ...in plants (Montgomery et al. 2020), and H3K9me2 mark took over the constitutive silencing, leading to the observed dichotomy between facultative and constitutive heterochromatin (Déléris et al. 2021). Mutants of MET1, a major player in constitutive heterochromatin establishment, showed compensation by H3K27...
  4. ...reduced EZH2 binding as well as histone 3 lysine 27 (H3K27) trimethylation level at SETDB1 solo peaks and facilitated neural differentiation. Furthermore, we found that H3K27me3 inhibits SETDB1 methyltransferase activity. The currently identified reciprocal action between SETDB1 and PRC2 reveals a novel...
  5. ...of heterochromatin, namely, the histone H3 lysine 9 methyltransferase DIM-5, Heterochromatin Protein 1 (HP1), which specifically binds to the product of DIM-5 (trimethylated H3 lysine 9 [H3K9me3]), and DIM-3 (importin alpha), which is involved in DIM-5 localization. The average genome configuration of the wild...
  6. ...Plasticity in patterns of histone modifications and chromosomal proteins in Drosophila heterochromatin Nicole C. Riddle 1 , 9 , Aki Minoda 2 , 9 , Peter V. Kharchenko 3 , 9 , Artyom A. Alekseyenko 4 , Yuri B. Schwartz 5 , 6...
  7. ...; Mattei et al. 2022; Shang and He 2022). Histone methylation, central to defining chromatin states, distinguishes transcriptionally active euchromatin from repressive heterochromatin. Histone methylation occurs at specific lysine residues of histones H3, H4, and H2B, including H3K4, H3K9, H3K27, H3K36, H4...
  8. ...and are overall gene-poor and transcriptionally inactive (Guelen et al. 2008; Meuleman et al. 2013; Lund et al. 2014). Accordingly, LADs are enriched in histone modifications marking silent chromatin, including H3 lysine 9 di- or trimethylation (H3K9me2/3) (Guelen et al. 2008; Kind et al. 2013; Sadaie et al. 2013...
  9. ...PTMs. The MPHOSPH8 Chromo domain binds specifically to histone H3 trimethylated on lysine 9 through the same conserved recognition mechanism as the Chromo domains of the HP1 protein family (including human CBX1) (Li et al. 2011). On the peptide array, MPHOSPH8 Chromo bound most prominently to H3K9me3...
  10. ...for this article.] The original definition of heterochromatin was wholly derived from cytological studies, identifying it as unusually compacted nuclear material as opposed to the less-condensed euchromatin. Heterochromatin in the eukaryotic is subclassified as facultative and constitutive. Whereas sites...
