| - | [[ | + | [[https://www.uniprot.org/uniprot/RRP6_YEAST RRP6_YEAST]] Nuclear-specific catalytic component of the RNA exosome complex which has 3'->5' exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events. In the nucleus, the RNA exosome complex is involved in proper maturation of stable RNA species such as rRNA, snRNA and snoRNA, in the elimination of RNA processing by-products and non-coding 'pervasive' transcripts, such as antisense RNA species and cryptic unstable transcripts (CUTs), and of mRNAs with processing defects, thereby limiting or excluding their export to the cytoplasm. The catalytic inactive RNA exosome core complex of 9 subunits (Exo-9) is proposed to play a pivotal role in the binding and presentation of RNA for ribonucleolysis, and to serve as a scaffold for the association with catalytic subunits and accessory proteins or complexes. RRP6 has 3'-5' exonuclease activity which is not modulated upon association with Exo-9 suggesting that the complex inner RNA-binding path is not used to access its active site.<ref>PMID:9582370</ref> <ref>PMID:10465791</ref> <ref>PMID:10611239</ref> <ref>PMID:15489286</ref> |
