Taxonomy
DescriptionThis compound belongs to the class of organic compounds known as pyrazolopyrimidines. These are compounds containing a pyrazolopyrimidine skeleton, which consists of a pyrazole fused to a pyrimidine. Pyrazole is 5-membered ring consisting of three carbon atoms and two adjacent nitrogen centers. Pyrimidine is 6-membered ring consisting of four carbon atoms and two adjacent nitrogen atoms at the 1- and 3- ring position.

General Function:
Protein homodimerization activity
Specific Function:
Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway.
