DESCRIPTION: RecName: Full=Pterin-4-alpha-carbinolamine dehydratase 2; Short=PHS 2; EC=; AltName: Full=4-alpha-hydroxy-tetrahydropterin dehydratase 2; AltName: Full=DcoH-like protein DCoHm; AltName: Full=Dimerization cofactor of hepatocyte nuclear factor 1 from muscle; AltName: Full=HNF-1-alpha dimerization cofactor;
FUNCTION: Involved in tetrahydrobiopterin biosynthesis. Seems to both prevent the formation of 7-pterins and accelerate the formation of quinonoid-BH2 (By similarity).
FUNCTION: Regulates the dimerization of homeodomain protein HNF-1- alpha and enhances its transcriptional activity.
CATALYTIC ACTIVITY: (6R)-6-(L-erythro-1,2-dihydroxypropyl)- 5,6,7,8-tetrahydro-4a-hydroxypterin = (6R)-6-(L-erythro-1,2- dihydroxypropyl)-7,8-dihydro-6H-pterin + H(2)O.
SUBUNIT: Homotetramer. Interacts with DYRK1B.
INTERACTION: Q9Y463:DYRK1B; NbExp=2; IntAct=EBI-634289, EBI-634187;
SIMILARITY: Belongs to the pterin-4-alpha-carbinolamine dehydratase family.
SEQUENCE CAUTION: Sequence=AAM18136.1; Type=Erroneous initiation;

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

ModBase Predicted Comparative 3D Structure on Q9H0N5
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
