Histone methyltransferases

Histone methyltransferases are enzymes that add methyl groups to histone proteins, which are crucial for packaging DNA in our cells. This modification influences how tightly or loosely DNA is wrapped around histones, affecting gene accessibility and expression. By regulating which genes are turned on or off, histone methyltransferases play a key role in various biological processes, including development, cell differentiation, and response to environmental signals. Dysregulation of these enzymes can lead to diseases such as cancer, making them important targets for research and potential therapies.
