OGT as potential novel target: Structure, function and inhibitors

O-linked N-acetylglucosamine transferase (OGT), a key protein in O-linked N-acetylglucosamine (O-GlcNAc) post-translational modification, catalyzes O-GlcNAcylation by linking GlcNAc from glycosyl donors to protein Ser/Thr residues to regulate multiple biological processes. OGT has become a popular research topic in the field of glycobiology as a potential target. This report consists of three parts, namely: the basic information of OGT, the relationship between OGT and diseases, and the research progress of OGT inhibitors. This report aims to improve the understanding of OGT-related fields from the perspective of its structure. OGT inhibitors could aid the effective and efficient investigation of the O-GlcNAcylation mechanism, and provide new ideas and methods for the treatment of related diseases.
