  • Application notes
    Is unsuitable for Flow Cyt or ICC.
  • Target

    • 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.
    • Pathway
      Purine metabolism; IMP biosynthesis via salvage pathway; IMP from hypoxanthine: step 1/1.
    • Involvement in disease
      Defects in HPRT1 are the cause of Lesch-Nyhan syndrome (LNS) [MIM:300322]. LNS is characterized by complete lack of enzymatic activity that results in hyperuricemia, choreoathetosis, mental retardation, and compulsive self-mutilation.
      Defects in HPRT1 are the cause of gout HPRT-related (GOUT-HPRT) [MIM:300323]; also known as HPRT-related gout or Kelley-Seegmiller syndrome. Gout is characterized by partial enzyme activity and hyperuricemia.
    • Sequence similarities
      Belongs to the purine/pyrimidine phosphoribosyltransferase family.
