Summary We are characterising the function of O-GlcNAc glycosylation in immune cells by identifying changes in patterns of glycosylation in different metabolic states and upon encounter of pathogens.
O-GlcNAc glycosylation involves addition of a single sugar, β-N-acetylglucosamine, to serine or threonine residues of proteins. It is a unique type of glycosylation found on nuclear and cytoplasmic proteins. The addition and removal of O-GlcNAc is catalysed by O-GlcNAc transferase (OGT) and O-GlcNAse (OGA) respectively. It is a reversible modification akin to phosphorylation. Indeed, O-GlcNAc glycosylation occurs in dynamic interplay with phosphorylation, either on the same or adjacent residues. The cross-talk between these two modifications in turn regulates various cellular processes. We are characterising the function of O-GlcNAc glycosylation in immune cells by identifying changes in patterns of glycosylation in different metabolic states and upon encounter of pathogens. The function of glycosylated proteins will be further studied to understand the relevance of their O-GlcNAc status in various immune cell activities.
