PNP - purine nucleoside phosphorylase Gene

Homo sapiens

Also known as NP; PUNP; PRO1837

Gene ID: 4860 | Gene type: protein coding

About PNP

Cytogenetic location: 14q11.2 Genomic coordinates (GRCh38): 14:20,469,406-20,477,089 (from NCBI)

This gene has 11 transcripts (splice variants), 540 orthologues, 1 paralogue and is associated with 2 phenotypes. Broad expression in bone marrow (RPKM 94.2), kidney (RPKM 44.4) and 18 other tissues.

Summary

This gene encodes an Enzyme which reversibly catalyzes the phosphorolysis of purine nucleosides. The Enzyme is trimeric, containing three identical subunits. Mutations which result in nucleoside phosphorylase deficiency result in defective T-cell (cell-mediated) immunity but can also affect B-cell immunity and antibody responses. Neurologic disorders may also be apparent in patients with immune defects. A known polymorphism at aa position 51 that does not affect Enzyme activity has been described. A pseudogene has been identified on chromosome 2. [provided by RefSeq, Jul 2008]
