GMP reductase 2 (GMPR2)

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 (PubMed:12009299, PubMed:12669231, PubMed:16359702, PubMed:22037469).

Plays a role in modulating cellular differentiation (PubMed:12669231). .
