Identification
HMDB Protein ID CDBP00881
Secondary Accession Numbers Not Available
Name GTP cyclohydrolase 1
Description Not Available
Synonyms
  1. GTP cyclohydrolase I
  2. GTP-CH-I
Gene Name GCH1
Protein Type Enzyme
Biological Properties
General Function Involved in GTP cyclohydrolase I activity
Specific Function Positively regulates nitric oxide synthesis in umbilical vein endothelial cells (HUVECs). May be involved in dopamine synthesis. May modify pain sensitivity and persistence. Isoform GCH-1 is the functional enzyme, the potential function of the enzymatically inactive isoforms remains unknown.
