About

* O-mannosyl glycans are a type of O-glycan in which the reducing terminal mannose is attached to Ser/Thr.
* POMGnT1 catalyzes the transfer of β1,2GlcNAc from UDP-GlcNAc to O-mannose of glycoproteins.
* POMGnT1 deficiency results in muscle-eye-brain disease (MEB), a form of congenital muscular dystrophy/ a-dystroglycanopathy.
* POMGnT1 cannot recognize 6P-Man-peptide as an acceptor. Thus O-mannose phosphorylation occurs after the formation of GlcNAcβ1-2Man linkage.
