OGT

O-linked N-acetylglucosaminyltransferase; O-GlcNAc transferase

OGT (O-GlcNAc transferase) catalyzes the addition of the O-GlcNAc post-translational modification to proteins. O-GlcNAcylation is a dynamic form of protein glycosylation which involves the addition of β-d-N-acetylglucosamine (GlcNAc) via an O-linkage to serine or threonine residues of nuclear, cytoplasmic, mitochondrial and transmembrane proteins.
