It has been reported that one downstream effector produced from glucose is uridine diphosphate-N-acetly glucosamine (UDP-GlcNAc) via the hexoamine biosynthetic pathway (HBP). The dynamic cycle of addition and removal of O-linked-N-acetlyglucosamine (O-GlcNAc) to Ser/Thr residues is involved in regulating nuclear and cytoplasmic proteins. Nucleocytoplasmic O-linked GlcNAc transferases(ncOGT) which add a single GlcNAc to hydroxyl groups of serine and threonine residues. ncOGT is characterized by an amino terminuns bearing tetratricopeptide repeats (TPR), possible nuclear trafficking motifs, and a catalytic domain within its C-terminus. Interestingly, O-GlcNAc glycosylation occurs in nucelocytoplsmic O-linked GlcNAc transferase (ncOGT) as well and several sites have been identified mainly within TPR domain. We found O-GlcNAcylated site in ncOGT outside of TPR by using Q-TOF MS. Now we focus on the activities and function of ncOGT by mutagenesis studies. This ongoing effort would give us clear understanding of the key enzyme of O-GlcNAc metabolism and how the O-GlcNAc modification may be regulated.
