Description

The ST6GALNAC2 (ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 2) is a protein-coding gene located on chromosome 17.

Alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 2 is an enzyme that in humans is encoded by the ST6GALNAC2 gene.

ST6GALNAC2 catalyzes the transfer of N-acetylneuraminyl groups onto glycan chains in glycoproteins. It exhibits a preference for N-acetylgalactosamine (GalNAc) residues that have been modified by the addition of galactose or galactose followed by sialic acid in an alpha-2,3 linkage.

ST6GALNAC2 is also known as SAITL1, SIAT7, SIAT7B, SIATL1, ST6GalNAII, STHM.
