What is Protein O-GlcNAcylation?
Protein O-GlcNAcylation is catalyzed by O-GlcNAc transferase (OGT) and removed by O-GlcNAcase (OGA), forming a dynamic modification cycle similar to phosphorylation. This modification:
- Regulates transcription factors, chromatin-associated proteins, signaling molecules, and metabolic enzymes
- Interacts with phosphorylation to shape cellular responses
- Responds to nutrient levels, stress conditions, and metabolic status
- Plays roles in diabetes, neurodegeneration, cardiovascular disorders, and cancer
Due to its low abundance and rapid cycling, high sensitivity and selective enrichment are required for accurate identification.
