CDCA7's Role in DNA Methylation Maintenance Revealed in Recent Study

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.

Cryo-EM Reveals CDCA7's Hemimethylation Sensing in Nucleosome Core Particles

DNA methylation, a process by which methyl groups are added to DNA molecules, is essential for the maintenance of DNA and the overall health of an organism. Disruptions in the standard DNA methylation patterns can lead to immunodeficiency and diseases such as cancer.
