Gene: PNP (purine nucleoside phosphorylase) Homo sapiens
Symbol: PNP
Name: purine nucleoside phosphorylase
Description: Exhibits several functions, including phosphate ion binding activity; purine nucleobase binding activity; and purine-nucleoside phosphorylase activity. Involved in several processes, including interleukin-2 secretion; nucleobase-containing small molecule metabolic process; and positive regulation of T cell activation. Localizes to the cytosol. Implicated in purine nucleoside phosphorylase deficiency and purine-pyrimidine metabolic disorder.
Type: protein-coding
RefSeq Status: REVIEWED
