CDCA7 identified as key player in hemimethylation sensing
DNA
Rockefeller University Aug 28 2024 DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and a major way that DNA is epigenetically marked. Epigenetic modifications can act as on-off switches to regulate gene expression and help generate diverse cell types without changing the underlying DNA sequence. It is how the body ensures that brain-related genes don't get turned on in heart cells, for example. For this reason, maintenance of the DNA
