Description Not Available
Synonyms
  1. HLUG25
  2. Hyodeoxycholic acid-specific UDPGT
  3. UDPGT 2B4

Gene Name UGT2B4
Protein Type Enzyme
Biological Properties
General Function Involved in transferase activity, transferring hexosyl groups
Specific Function UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme is active on polyhydroxylated estrogens (such as estriol, 4-hydroxyestrone and 2-hydroxyestriol) and xenobiotics (such as 4-methylumbelliferone, 1-naphthol, 4-nitrophenol, 2-aminophenol, 4-hydroxybiphenyl and menthol). It is capable of 6 alpha-hydroxyglucuronidation of hyodeoxycholic acid.
