Hypoxanthine-guanine phosphoribosyltransferase (P00493)

Uniprot ID P00493
Protein Name Hypoxanthine-guanine phosphoribosyltransferase
Gene Name Hprt1
Species Mus musculus (Mouse)
Signal peptide(a) N Secretome P(b) 0.847
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 (By similarity). .

Back
(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
