PCBD1

Pterin-4-alpha-carbinolamine dehydratase is an enzyme that in humans is encoded by the "PCBD1" gene.
Function.
This gene encodes pterin-4 alpha-carbinolamine dehydratase, an enzyme involved in phenylalanine hydroxylation. A deficiency of this enzyme leads to hyperphenylalaninemia. The enzyme regulates the homodimerization of the transcription factor hepatocyte nuclear factor 1 (HNF1).
Interactions.
PCBD1 has been shown to interact with DYRK1B and HNF1A.
