Protein attributes

Sequence length	345 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

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.
Catalytic activity	Inosine 5'-phosphate + NH(3) + NADP(+) = guanosine 5'-phosphate + NADPH.
Subunit structure	Homotetramer By similarity.
Sequence similarities	Belongs to the IMPDH/GMPR family.
