![عکس صفحه اول مقاله: O-GlcNAcylation at promoters, nutrient sensors, and transcriptional regulation O-GlcNAcylation at promoters, nutrient sensors, and transcriptional regulation](/preview/png/1946476.png)
• This review article discusses recent advances in the links between O-GlcNAc and transcriptional regulation.
• Discusses several systems to illustrate O-GlcNAc dynamics: Tet proteins, MLL complexes, circadian clock proteins and RNA pol II.
• Suggests that promoters are nutrient sensors.
Post-translational modifications play important roles in transcriptional regulation. Among the less understood PTMs is O-GlcNAcylation. Nevertheless, O-GlcNAcylation in the nucleus is found on hundreds of transcription factors and coactivators and is often found in a mutually exclusive ying–yang relationship with phosphorylation. O-GlcNAcylation also links cellular metabolism directly to the proteome, serving as a conduit of metabolic information to the nucleus. This review serves as a brief introduction to O-GlcNAcylation, emphasizing its important thematic roles in transcriptional regulation, and highlights several recent and important additions to the literature that illustrate the connections between O-GlcNAc and transcription.
