General annotation (Comments)

Function

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. Ref.5

Catalytic activity

UDP-N-acetyl-alpha-D-glucosamine + O-alpha-D-mannosylprotein = UDP + N-acetyl-beta-D-glucosaminyl-(1->4)-O-alpha-D-mannosylprotein. Ref.5

Pathway

Protein modification; protein glycosylation.

Subcellular location

Endoplasmic reticulum membrane; Single-pass type II membrane protein Ref.5.

Tissue specificity

Highly expressed in the brain, muscle, heart, and kidney in both fetus and adult. In the brain, highest expression in the cortex and cerebellum. Highly expressed in the pancreas. Ref.6

Involvement in disease

Muscular dystrophy-dystroglycanopathy congenital with brain and eye anomalies A8 (MDDGA8) [MIM:614830]: An 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.
Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.6

Sequence similarities

Belongs to the glycosyltransferase 61 family.

Contains 1 fibronectin type-III domain.
