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.,online information:Beta-1,4 N-acetylgalactosaminyltransferase 2,online information:GlycoGene database,pathway:Protein modification; protein glycosylation.,similarity:Belongs to the glycosyltransferase 2 family.,tissue specificity:Widely expressed. Highly expressed in colon and to a lesser extent in kidney, stomach, ileum and rectum.,
Golgi apparatus membrane ; Single-pass type II membrane protein .
