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

Gene

POMGNT2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

O-linked mannose beta-1,4-N-acetylglucosaminyltransferase that tranfers UDP-N-acetyl-D-glucosamine to the 4-position of the mannose to generate 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 required for binding laminin G-like domain-containing extracellular proteins with high affinity.1 Publication

Catalytic activityi

UDP-N-acetyl-alpha-D-glucosamine + O-alpha-D-mannosylprotein = UDP + N-acetyl-beta-D-glucosaminyl-(1->4)-O-alpha-D-mannosylprotein.1 Publication

Involvement in diseasei

Muscular dystrophy-dystroglycanopathy congenital with brain and eye anomalies A81 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAn autosomal recessive disorder characterized by congenital muscular dystrophy associated with cobblestone lissencephaly and other brain anomalies, eye malformations, profound mental retardation, and death usually in the first years of life. Included diseases are the more severe Walker-Warburg syndrome and the slightly less severe muscle-eye-brain disease.
