Gene: PNPT1 (polyribonucleotide nucleotidyltransferase 1) Homo sapiens
Symbol: PNPT1
Name: polyribonucleotide nucleotidyltransferase 1
Description: Exhibits 3'-5'-exoribonuclease activity; RNA binding activity; and polyribonucleotide nucleotidyltransferase activity. Involved in several processes, including RNA metabolic process; cellular response to interferon-beta; and positive regulation of cellular catabolic process. Localizes to cytosol; mitochondrial degradosome; and mitochondrial intermembrane space. Implicated in autosomal recessive nonsyndromic deafness 70 and combined oxidative phosphorylation deficiency 13.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: 3'-5' RNA exonuclease OLD35; COXPD13; DFNB70; DKFZp762K1914; old-35; OLD35; PNPASE; PNPase 1; PNPase old-35; polynucleotide phosphorylase 1; polynucleotide phosphorylase-like protein; polyribonucleotide nucleotidyltransferase 1, mitochondrial
