ST6GALNAC1

Alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 1 is an enzyme that in humans is encoded by the ST6GALNAC1 gene.^[5] This enzyme adds a N-acetylneuraminic acid (Neu5Ac, a sialic acid) to an O-linked N-acetylgalactosamine (GalNAc) on a peptide/proteins (also called Tn antigen) with an α2-6 linkage to produce the sialyl-Tn antigen. It has been shown that the enzyme prefers threonine over serine containing GalNAc residues.^[6][7]
