HS3ST6 is a symbol for the gene, Heparan sulfate-glucosamine 3-sulfotransferase 6, in humans. Other names include: Heparan sulfate glucosamine 3-O-sulfotransferase 6; Heparan sulfate D-glucosaminyl 3-O-sulfotransferase 6; 3-OST-6; Heparan sulfate 3-O-sulfotransferase 6; h3-OST-6; Heparan sulfate glucosamine 3-O-sulfotransferase 6 ; HS3ST5; heparan sulfate (glucosamine) 3-O-sulfotransferase 6. The encoded protein is an enzyme with an amino acid length of 342 and a mass of 37.2 kDa. Other isoforms may exist. HS3ST6 is a member of the Sulfotransferase 1 family. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog, Chicken.
