UDP-GalNAc:beta-1,3-N-acetylgalactosaminyltransferase 2

Gene

b3galnt2

Organism
Danio rerio (Zebrafish) (Brachydanio rerio)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Beta-1,3-N-acetylgalactosaminyltransferase that synthesizes a unique carbohydrate structure, GalNAc-beta-1-3GlcNAc, on N- and O-glycans. Has no galactose nor galactosaminyl transferase activity toward any acceptor substrate. Involved in alpha-dystroglycan (dag1) glycosylation.1 Publication

Catalytic activityi

UDP-N-acetyl-alpha-D-galactosamine + 3-O-(N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl)-L-threonyl-[protein] = UDP + 3-O-(N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl)-L-threonyl-[protein].By similarity
