Background
| Function | FUNCTION: 3'-to-5'exoribonuclease that preferentially degrades DNA and RNA oligonucleotides composed of only two nucleotides (PubMed:31588022, PubMed:30926754, PubMed:32365187, PubMed:23741365). Binds and degrades longer oligonucleotides with a lower affinity (PubMed:31588022, PubMed:30926754, PubMed:32365187). Plays dual roles in mitochondria, scavenging nanoRNAs (small RNA oligonucleotides of <5 nucleotides) that are produced by the degradosome and clearing short RNAs that are generated by RNA processing (PubMed:31588022, PubMed:30926754, PubMed:32365187). Essential for correct initiation of mitochondrial transcription, degrading mitochondrial RNA dinucleotides to prevent RNA-primed transcription at non-canonical sites in the mitochondrial genome (PubMed:31588022). Essential for embryonic development (By similarity). {ECO:0000250|UniProtKB:Q9D8S4, ECO:0000269|PubMed:23741365, ECO:0000269|PubMed:30926754, ECO:0000269|PubMed:31588022, ECO:0000269|PubMed:32365187}.; FUNCTION: [Isoform 3]: 3'-to-5'exoribonuclease that preferentially degrades DNA and RNA oligonucleotides composed of only two nucleotides. {ECO:0000269|PubMed:10851236, ECO:0000269|PubMed:16682444}. |
