O-GlcNAcylation is a dynamic post-translational modification involving the attachment of N-acetylglucosamine (GlcNAc) to serine or threonine residues on nuclear and cytoplasmic proteins. This process serves as a critical nutrient and stress sensor that influences a wide range of cellular functions, impacting processes such as transcription, protein degradation, and cellular signaling pathways. The dynamic nature of […]
