Summary
PNPT1 (polyribonucleotide nucleotidyltransferase 1, HGNC:23166) is a protein-coding gene on chromosome 2p16.1, encoding Polyribonucleotide nucleotidyltransferase 1, mitochondrial (Q8TCS8). RNA-binding protein implicated in numerous RNA metabolic processes. It is a selective cancer dependency (DepMap: 89.1% of cell lines).
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. Mutations in this gene have been associated with combined oxidative phosphorylation deficiency-13 and autosomal recessive nonsyndromic deafness-70. Related pseudogenes are found on chromosomes 3 and 7.

Function. RNA-binding protein implicated in numerous RNA metabolic processes. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3’-to-5’ direction. Mitochondrial intermembrane factor with RNA-processing exoribonulease activity. Component of the mitochondrial degradosome (mtEXO) complex, that degrades 3’ overhang double-stranded RNA with a 3’-to-5’ directionality in an ATP-dependent manner. Involved in the degradation of non-coding mitochondrial transcripts (MT-ncRNA) and tRNA-like molecules. Required for correct processing and polyadenylation of mitochondrial mRNAs. Plays a role as a cytoplasmic RNA import factor that mediates the translocation of small RNA components, like the 5S RNA, the RNA subunit of ribonuclease P and the mitochondrial RNA-processing (MRP) RNA, into the mitochondrial matrix. Plays a role in mitochondrial morphogenesis and respiration; regulates the expression of the electron transport chain (ETC) components at the mRNA and protein levels. In the cytoplasm, shows a 3’-to-5’ exoribonuclease mediating mRNA degradation activity; degrades c-myc mRNA upon treatment with IFNB1/IFN-beta, resulting in a growth arrest in melanoma cells. Regulates the stability of specific mature miRNAs in melanoma cells; specifically and selectively degrades miR-221, preferentially. Also plays a role in RNA cell surveillance by cleaning up oxidized RNAs. Binds to the RNA subunit of ribonuclease P, MRP RNA and miR-221 microRNA.
Subunit / interactions. Homotrimer; in free form. Homooligomer. Component of the mitochondrial degradosome (mtEXO) complex which is a heteropentamer containing 2 copies of SUPV3L1 and 3 copies of PNPT1. As part of the mitochondrial degradosome complex, interacts with GRSF1 in an RNA-dependent manner; the interaction enhances the activity of the complex. Interacts with TCL1A; the interaction has no effect on PNPT1 exonuclease activity.
Subcellular location. Cytoplasm. Mitochondrion matrix. Mitochondrion intermembrane space.
Disease relevance. Combined oxidative phosphorylation deficiency 13 (COXPD13) [MIM:614932] A mitochondrial disorder characterized by early onset severe encephalomyopathy, dystonia, choreoathetosis, bucofacial dyskinesias and combined mitochondrial respiratory chain deficiency. Nerve conductions velocities are decreased. Levels of plasma and cerebrospinal fluid lactate are increased. The disease is caused by variants affecting the gene represented in this entry. Deafness, autosomal recessive, 70, with or without adult-onset neurodegeneration (DFNB70) [MIM:614934] A form of non-syndromic deafness characterized by severe, bilateral hearing impairment with prelingual onset, resulting in inability to acquire normal speech. Affected individuals may develop a neurodegenerative disease in adulthood, including ataxia with loss of ambulation, optic atrophy, dystonia or spasticity, and cognitive decline with psychiatric features. The disease is caused by variants affecting the gene represented in this entry. Spinocerebellar ataxia 25 (SCA25) [MIM:608703] An autosomal dominant form of spinocerebellar ataxia, a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA25 is characterized by the onset of lower limb ataxia and gait difficulties in the first few decades of life, although later onset has been reported. There is incomplete penetrance and variable expressivity, even within families. The disease is caused by variants affecting the gene represented in this entry. Both genetic variants associated so far with this disease are affecting splicing.
Induction. Up-regulated in cells upon senescence and terminal differentiation. Up-regulated after treatment with IFNB1/IFN-beta.
Similarity. Belongs to the polyribonucleotide nucleotidyltransferase family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 114 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
