General Information

Term

protein O-linked glycosylation via N-acetylglucosamine

ID (Ontology)

GO:7770074 (Gene Ontology)

Definition

A glycoprotein biosynthetic process in which a single N-acetylglucosamine is covalently linked via a beta-glycosidic bond to the oxygen atom of a serine or threonine side chain in a protein, resulting in the formation of a protein O-linked glycan. The sugar is not elongated into a larger oligosaccharide chain.[ PubMed:35536957 ]

Also Known As

"protein O-linked GlcNAcylation" ; "protein O-linked N-acetylglucosaminylation"
