Minireview series on the thirtieth anniversary of research on O-GlcNAcylation of nuclear and cytoplasmic proteins: Nutrient regulation of cellular metabolism and physiology by O-GlcNAcylation

Hart GW. J Biol Chem. 2014 Dec 12;289(50):34422-3. doi: 10.1074/jbc.R114.609776. PMID: 25336646

The dynamic cycling of N-acetylglucosamine (termed O-GlcNAcylation) on serine or threonine residues of nuclear or cytoplasmic proteins serves as a nutrient sensor, both independently and also via its interplay with other post-translational modifications, to regulate signaling, transcription, and cellular physiology. Emerging evidence suggests that dysregulation of this ubiquitous post-translational modification contributes to the etiology of some the most important human chronic diseases.
