CC   -!- FUNCTION: RNA-binding protein implicated in numerous RNA metabolic
CC       processes. Catalyzes the phosphorolysis of single-stranded
CC       polyribonucleotides processively in the 3'-to-5' direction.
CC       Mitochondrial intermembrane factor with RNA-processing exoribonulease
CC       activity. Component of the mitochondrial degradosome (mtEXO) complex,
CC       that degrades 3' overhang double-stranded RNA with a 3'-to-5'
CC       directionality in an ATP-dependent manner. Involved in the degradation
CC       of non-coding mitochondrial transcripts (MT-ncRNA) and tRNA-like
CC       molecules (By similarity). Required for correct processing and
CC       polyadenylation of mitochondrial mRNAs. Plays a role as a cytoplasmic
CC       RNA import factor that mediates the translocation of small RNA
CC       components, like the 5S RNA, the RNA subunit of ribonuclease P and the
CC       mitochondrial RNA-processing (MRP) RNA, into the mitochondrial matrix.
CC       Plays a role in mitochondrial morphogenesis and respiration; regulates
CC       the expression of the electron transport chain (ETC) components at the
CC       mRNA and protein levels. In the cytoplasm, shows a 3'-to-5'
CC       exoribonuclease mediating mRNA degradation activity; degrades c-myc
CC       mRNA upon treatment with IFNB1/IFN-beta, resulting in a growth arrest
CC       in melanoma cells. Regulates the stability of specific mature miRNAs in
CC       melanoma cells; specifically and selectively degrades miR-221,
CC       preferentially. Also plays a role in RNA cell surveillance by cleaning
CC       up oxidized RNAs. Binds to the RNA subunit of ribonuclease P, MRP RNA
CC       and miR-221 microRNA. {ECO:0000250|UniProtKB:Q8TCS8,
CC       ECO:0000269|PubMed:20691904}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=phosphate + RNA(n+1) = a ribonucleoside 5'-diphosphate +
CC         RNA(n); Xref=Rhea:RHEA:22096, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC         COMP:17342, ChEBI:CHEBI:43474, ChEBI:CHEBI:57930, ChEBI:CHEBI:140395;
CC         EC=2.7.7.8;
CC   -!- SUBUNIT: Homotrimer; in free form. Homooligomer. Component of the
CC       mitochondrial degradosome (mtEXO) complex which is a heteropentamer
CC       containing 2 copies of SUPV3L1 and 3 copies of PNPT1. As part of the
CC       mitochondrial degradosome complex, interacts with GRSF1 in an RNA-
CC       dependent manner; the interaction enhances the activity of the complex.
CC       Interacts with TCL1A; the interaction has no effect on PNPT1
CC       exonuclease activity. {ECO:0000250|UniProtKB:Q8TCS8}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q8TCS8}.
CC       Mitochondrion matrix {ECO:0000250|UniProtKB:Q8TCS8}. Mitochondrion
CC       intermembrane space {ECO:0000269|PubMed:16966381}; Peripheral membrane
CC       protein {ECO:0000269|PubMed:16966381}.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative splicing; Named isoforms=2;
CC       Name=1;

CC       Name=2;
CC         IsoId=Q8K1R3-2; Sequence=VSP_013639, VSP_013640;
CC   -!- DISRUPTION PHENOTYPE: Mice show alteration in the mechanisms of
CC       polycistronic mtRNAs processing in mitochondria, resulting in fewer
CC       mature mtRNAs and a reduction in electron transport chain (ETC)
CC       components formation. {ECO:0000269|PubMed:20691904}.
CC   -!- SIMILARITY: Belongs to the polyribonucleotide nucleotidyltransferase
CC       family. {ECO:0000305}.
