Identification
HMDB Protein ID HMDBP00678
Secondary Accession Numbers
  • 5951
Name GMP reductase 2
Synonyms
  1. Guanosine 5'-monophosphate oxidoreductase 2
  2. Guanosine monophosphate reductase 2
Gene Name GMPR2
Protein Type Enzyme
Biological Properties
General Function Involved in catalytic activity
Specific Function Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides. Plays a role in modulating cellular differentiation.
