Protein Name: Hypoxanthine-guanine phosphoribosyltransferase

UniprotKB/SwissProt ID: HPRT_HUMAN (P00492)

Gene Name: HPRT1

Synonyms: HPRT

Organism: Homo sapiens (Human).

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.

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm.
