Putative 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 promoter-upstream transcripts (PROMPTs), and of mRNAs with processing defects, thereby limiting or excluding their export to the cytoplasm. The RNA exosome may be involved in Ig class switch recombination (CSR) and/or Ig variable region somatic hypermutation (SHM) by targeting AICDA deamination activity to transcribed dsDNA substrates. In the cytoplasm, the RNA exosome complex is involved in general mRNA turnover and specifically degrades inherently unstable mRNAs containing AU-rich elements (AREs) within their 3' untranslated regions, and in RNA surveillance pathways, preventing translation of aberrant mRNAs. It seems to be involved in degradation of histone mRNA. DIS3 has both 3'-5' exonuclease and endonuclease activities.

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. In the cytoplasm, the RNA exosome complex is involved in general mRNA turnover and in RNA surveillance pathways, preventing translation of aberrant mRNAs. 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. DIS3 has both 3'-5' exonuclease and endonuclease activities. The exonuclease activity of DIS3 is down-regulated upon association with Exo-9 possibly involving a conformational change in the catalytic domain and threading of the RNA substrate through the complex central channel. Structured substrates can be degraded if they have a 3' single-stranded extension sufficiently long (such as 35 nt poly(A)) to span the proposed complex inner RNA-binding path and to reach the exonuclease site provided by dis3 (By similarity). Implicated in mitotic control. Essential for cell division and spore germination. May be involved in regulating protein dephosphorylation during mitosis.

This family consists of an exoribonuclease, ribonuclease R, also called VacB. It is one of the eight exoribonucleases reported in E. coli and is broadly distributed throughout the bacteria. In E. coli, double mutants of this protein and polynucleotide phosphorylase are not viable. Scoring between trusted and noise cutoffs to the model are shorter, divergent forms from the Chlamydiae, and divergent forms from the Campylobacterales (including Helicobacter pylori) and Leptospira interrogans [Transcription, Degradation of RNA].

This model is defined to identify a pair of paralogous 3-prime exoribonucleases in E. coli, plus the set of proteins apparently orthologous to one or the other in other eubacteria. VacB was characterized originally as required for the expression of virulence genes, but is now recognized as the exoribonuclease RNase R (Rnr). Its paralog in E. coli and H. influenzae is designated exoribonuclease II (Rnb). Both are involved in the degradation of mRNA, and consequently have strong pleiotropic effects that may be difficult to disentangle. Both these proteins share domain-level similarity (RNB, S1) with a considerable number of other proteins, and full-length similarity scoring below the trusted cutoff to proteins associated with various phenotypes but uncertain biochemistry; it may be that these latter proteins are also 3-prime exoribonucleases [Transcription, Degradation of RNA].
