Research Abstract |
Glycosylation of proteins occurs in the lumens of the endoplasmic reticulum and the Golgi apparatus, which resulted in diverse structures of carbohydrate moieties. By contrast, addition of N-acetylglucosamine (GlcNAc) to serine and threonine is a unique glycosylation reaction occurred in nucleus and cytoplasm. We expressed a soluble glycosyltransferase having nuclear-localization signal in the cell and induced further elongation of GlcNAc residue. By using lectin affinity chromatography and mass spectrometry, we comprehensively identified O-GlcNAc modified proteins and their GlcNAc-modified amino acid residues.
