In mammals, it mainly occurs at palindromic CpG sites, but asymmetric methylation at non-CpG sites is also observed. Three enzymes are involved in the generation and maintenance of DNA methyl …
WebMar 16, 2024 · Moreover, recent studies suggest that allelic differences in genetic content can affect the activity of local CREs by using heterozygous single-nucleotide polymorphisms (SNPs) and their linked CpG methylation or GpC methyltransferase footprint from the same reads [8–10]. In principle, the genetic differences between two alleles may affect … At least four differently active DNA methyltransferases have been identified in mammals. They are named DNMT1, two isoforms transcribed from the DNMT3a gene: DNMT3a1 and DNMT3a2, and DNMT3b. Recently, another enzyme DNMT3c has been discovered specifically expressed in the male germline in the mouse.
