Name Pterin-4-alpha-carbinolamine dehydratase 2
Synonyms
  1. 4-alpha-hydroxy-tetrahydropterin dehydratase 2
  2. DcoH-like protein DCoHm
  3. Dimerization cofactor of hepatocyte nuclear factor 1 from muscle
  4. HNF-1-alpha dimerization cofactor

Gene Name PCBD2
Protein Type Enzyme
Biological Properties
General Function Involved in 4-alpha-hydroxytetrahydrobiopterin dehydratase activity
Specific Function Involved in tetrahydrobiopterin biosynthesis. Seems to both prevent the formation of 7-pterins and accelerate the formation of quinonoid-BH2 (By similarity). Regulates the dimerization of homeodomain protein HNF-1-alpha and enhances its transcriptional activity.
