  1. ...-base resolution methylation levels for individual CpG sites across the . These resources also annotate hypomethylated regions commonly linked to gene promoters, as well as allele-specific methylation patterns relevant to genomic imprinting. Notable examples include MethBase (Song et al. 2013), MethBank (Zhang et...

  2. ...for motifs with either methylated or unmethylated CpG sites (Hashimoto et al. 2014; Wang et al. 2017; Yin et al. 2017). As an illustration of this, global loss of DNA methylation in ES cells was shown to unmask previously inaccessible genomic binding sites for the TF NRF1 (Domcke et al. 2015). Moreover, DNA...
  3. ...and characterization of the proteins that can bind to DNA methylation (mC readers). Two protein domains were identified to confer the ability to bind to DNA methylation: methyl-binding domain (MBD), first identified in methyl-CpG-binding protein 2 (MeCP2) (Nan et al. 1993), and the SET and RING-associated (SRA) domain...
  4. ...content ≥50% and an observed-to-expected CpG ratio ≥0.6) (Gardiner-Garden and Frommer 1987), not all meet this formal definition. Each imprinting domain is thus controlled by an ICR. One of the key features of these ICRs is that they are methylated only on one of the two parental alleles, and it is widely...
  5. ...affect gene expression through epigenetic regulation. At the CpG islands of active gene promoters, R-loop formation helps establish an unmethylated state both by blocking the activity of DNA methyltransferase 1 (Grunseich et al. 2018) and by recruiting the demethylating enzyme TET1 through GADD45A (Arab...
  6. ...and CpG islands by remodelers and transcription factors in the Em-MYC cells. In contrast, the gene body gains in H2A.Z during tumorigenesis were reflected by losses of DNA methylation, which showed a similar expression-dependent pattern in the lymphoma cells as compared with the Em-MYC cells (Fig. 6B...
  7. ...ortholog of mammalian H2A.Z) at developmental loci (Fig. 3A–C; top 250 genes, Supplemental Table 4); intersecting of the respective top 800 genes displays a 40% overlap (correlation P-value < 0.001). GO term analysis showed H2AFV is highly enriched at the promoters of genes involved in transcription...
  8. ...(RdDM). Best studied in Arabidopsis thaliana, during RdDM, H3K9me2 and DNA methylation recruit the plant-specific RNA polymerases (Pol) IV and V. Pol IV transcripts are processed into 24 nt siRNAs, which, loaded into members of the AGO4/6 clade, target Pol V transcripts to guide the sequence...
  9. ...that methylate either CpG or GpC sites (Jessen et al. 2004; Kilgore et al. 2007; Small et al. 2014).To measure absolute occupancy, it is crucial that the RE- or DNMT-catalyzed reactions reach saturation, which requires that nucleosome dynamics are frozen. This is mostly true for ex vivo–prepared or in vitro...
  10. ...at lysine 119 (H2AK119ub1), whereas PRC2 methylates histone H3 on lysine 27 (H3K27me3). In vertebrates, PRC1 and PRC2 are targeted by various mechanisms to gene promoters, particularly those associated with nonmethylated CpG islands (CGIs) (Bracken and Helin 2009; Simon and Kingston 2013; Blackledge et al...
