B4GALNT2 (Beta-1,4-N-Acetyl-Galactosaminyltransferase 2) is a Protein Coding gene. Diseases associated with B4GALNT2 include Diffuse Interstitial Keratitis. Among its related pathways are Transport to the Golgi and subsequent modification and Metabolism of proteins. B4GALNT2 catalyzes the last step in the biosynthesis of the human Sd(a) antigen through the addition of an N-acetylgalactosamine residue via a beta-1,4 linkage to a subterminal galactose residue substituted with an alpha-2,3-linked sialic acid. B4GALNT2 also catalyzes the last step in the biosynthesis of the Cad antigen
