Lactylation: From Molecular Insights to Disease Relevance.

Lactylation, referring to the covalent coupling of the lactyl group with lysine residues, is a recently defined post-translational modification. It has been demonstrated that lactylation can alter protein transcription, thereby affecting the transmission of genetic information and ultimately exerting diverse effects on health and diseases. Here, we review the existing literature and summarize the characteristics and mechanisms of lactylation on both histone and non-histone proteins. We hope to explore lactylation targets for different diseases, thus providing potential clues for new therapeutic strategies.
