Description
  • Protein-linked O-mannose glycans are initiated by the covalent attachment of mannose to serine and threonine residues in the protein via alpha-linkages. Core M1 glycans consist of all O-mannose glycans in which O-mannose is extended with beta-1,2-linked N-acetylglucosamine (GlcNAc) but not with beta-1,6-linked GlcNAc. M1 structures do not directly bind key extracellular components but are essential as precursors for M2 structures, and they support the maturation of M3 glycans (Praissman & Wells 2014; Endo, 2019).
