Beta-1,3-N-acetylgalactosaminyltransferase 2 is a protein that in humans is encoded by the B3GALNT2 gene.
Function
This gene encodes a member of the glycosyltransferase 31 family. The encoded protein synthesizes GalNAc:beta-1,3GlcNAc, a novel carbohydrate structure, on N- and O-glycans. Alternatively spliced transcript variants that encode different isoforms have been described. .
Clinical significance
A mutation in B3GALNT2 is known to cause dystroglycanopathy congenital with brain and eye anomalies A11 (MDDGA11), which is an autosomal recessive muscular dystrophy.
