Protein methylation

Protein methylation is a biological process where a small chemical group called a methyl group is added to specific amino acids within a protein. This modification can influence the protein's function, activity, stability, and interactions with other molecules. Methylation often occurs on proteins involved in gene regulation, such as histones, impacting how genes are turned on or off. It is a dynamic and reversible process, playing a crucial role in various cellular functions, including development, response to environmental signals, and cell cycle regulation.
