Anti-B4GN2

beta-1,4-N-acetyl-galactosaminyltransferase 2(B4GALNT2) Homo sapiens 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 (Montiel et al., 2003 [PubMed 12678917]).[supplied by OMIM, Mar 2008], Protein 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. [The UniProt Consortium] Recommended dilutions: WB 1:500-2000 ELISA 1:5000-20000. Cellular localization: Golgi apparatus membrane , Single-pass type II membrane protein .
