Secondary Accession Numbers None
Name Beta-galactoside alpha-2,6-sialyltransferase 2
  1. Alpha 2,6-ST 2
  2. CMP-N-acetylneuraminate-beta-galactosamide-alpha-2,6-sialyltransferase 2
  3. ST6Gal II
  4. Sialyltransferase 2
  5. ST6GalII
  6. hST6Gal II
Gene Name ST6GAL2
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Transfers sialic acid from the donor of substrate CMP-sialic acid to galactose containing acceptor substrates. Has alpha-2,6-sialyltransferase activity toward oligosaccharides that have the Gal-beta-1,4-GlcNAc sequence at the non-reducing end of their carbohydrate groups, but it has weak or no activities toward glycoproteins and glycolipids.
