Protein-coding gene in the species Homo sapiens
Alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 1 is an enzyme that in humans is encoded by the ST6GALNAC1 gene .[ 5] N -acetylneuraminic acidsialic 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]
