Fukutin Protein, Mouse, Recombinant (His & Myc)

Catalyzes the transfer of CDP-ribitol to the distal N-acetylgalactosamine 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) . This constitutes the first step in the formation of the ribitol 5-phosphate tandem repeat which links the phosphorylated O-mannosyl trisaccharide to the ligand binding moiety composed of repeats of 3-xylosyl-alpha-1,3-glucuronic acid-beta-1. Required for normal location of POMGNT1 in Golgi membranes, and for normal POMGNT1 activity. May interact with and reinforce a large complex encompassing the outside and inside of muscle membranes. Could be involved in brain development (Probable) .
