Name Beta-1,4 N-acetylgalactosaminyltransferase 2
Description Not Available
Synonyms
  1. Sd(a) beta-1,4-GalNAc transferase
  2. UDP-GalNAc:Neu5Aca2-3Galb-R b1,4-N-acetylgalactosaminyltransferase
Gene Name B4GALNT2
Protein Type Enzyme
Biological Properties
General Function Involved in transferase activity, transferring hexosyl groups
Specific Function Involved in the synthesis of the Sd(a) antigen (Sia- alpha2,3-[GalNAc-beta1,4]Gal-beta1,4-GlcNAc), a carbohydrate determinant expressed on erythrocytes, the colonic mucosa and other tissues. Transfers a beta-1,4-linked GalNAc to the galactose residue of an alpha-2,3-sialylated chain
