Protein O-linked-mannose beta-1,4-N-acetylglucosaminyltransferase 2 (POMGNT2)

O-linked mannose beta-1,4-N- acetylglucosaminyltransferase that transports UDP-N-acetyl-D- glucosamine to the 4-position of the mannose to create N-acetyl- D-glucosamine-beta-1,4-O-D-mannosylprotein. Involved in the biosynthesis of the phosphorylated O-mannosyl trisaccharide (N- acetylgalactosamine-beta-3-N-acetylglucosamine-beta-4-(phosphate- 6-)mannose), a carbohydrate structure present in alpha- dystroglycan (DAG1), which is needed for binding laminin G-like domain-containing extracellular proteins with high affinity.
