Deskripsi

How histone modifications crosstalk with DNA methylation to regulate epigenomic patterning and genome stability in mammals remains elusive. Here, the authors show that DNA methyltransferase DNMT1 is a reader for histone H4K20 trimethylation via its BAH1 domain, which leads to optimal maintenance of DNA methylation at repetitive LINE-1 elements.
