SULT2B, or Sulfotransferase family 2B member 1, is a human gene encoded by SULT2B1. It may also be known as: Sulfotransferase family cytosolic 2B member 1; Sulfotransferase 2B1; Alcohol sulfotransferase; Hydroxysteroid sulfotransferase 2; ST2B1; HSST2; sulfotransferase family, cytosolic, 2B, member 1. The encoded protein is an enzyme with an amino acid length of 365 and a mass of 41.3 kDa. SULT2B is a member of the Sulfotransferase 1 family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog.
