QuickView for PNPase (gene)


Gene Symbol:
PNPT1 Homo sapiens Homo sapiens
Full name:
polyribonucleotide nucleotidyltransferase 1
Synonyms:
COXPD13, DFNB70, OLD35, PNPASE, old-35, polyribonucleotide nucleotidyltransferase 1, mitochondrial, 3'-5' RNA exonuclease OLD35, PNPase 1, PNPase old-35, polynucleotide phosphorylase 1, polynucleotide phosphorylase-like protein
Genomic Location:
Chr 2: 55715956-55774463
Description:
The protein encoded by this gene belongs to the evolutionary conserved polynucleotide phosphorylase family comprised of phosphate dependent 3'-to-5' exoribonucleases implicated in RNA processing and degradation. This enzyme is predominantly localized in the mitochondrial intermembrane space and is involved in import of RNA to mitochondria. Mutation...
