The ribonuclease polynucleotide phosphorylase can interact with small regulatory RNAs in both protective and degradative modes.
New
De Lay et al., Cambridge, United Kingdom. In Rna, Feb 2016
Many of the actions of these nucleic acids are mediated by well-characterized chaperones such as the Hfq protein, but genetic screens have also recently identified the 3'-to-5' exoribonuclease polynucleotide phosphorylase (PNPase) as an unexpected stabilizer and facilitator of sRNAs in vivo.

Review
New
Dehò et al., Milano, Italy. In Wiley Interdiscip Rev Rna, Feb 2016
UNASSIGNED: Polynucleotide phosphorylase (PNPase) is an exoribonuclease that catalyzes the processive phosphorolytic degradation of RNA from the 3'-end.
Molecular recognition of mRNA 5' cap by 3' poly(a)-specific ribonuclease (PARN) differs from interactions known for other cap-binding proteins.
New
Virtanen et al., Warsaw, Poland. In Biochim Biophys Acta, Feb 2016
Poly(A)-specific ribonuclease (PARN) is a dimeric exoribonuclease that efficiently degrades mRNA 3' poly(A) tails while also simultaneously interacting with the mRNA 5' cap.
P-TEFb regulation of transcription termination factor Xrn2 revealed by a chemical genetic screen for Cdk9 substrates.
New
Fisher et al., New York City, United States. In Genes Dev, Feb 2016
Among the RNA processing factors phosphorylated by Cdk9 was the 5'-to-3' "torpedo" exoribonuclease Xrn2, required in transcription termination by Pol II, which we validated as a bona fide P-TEFb substrate in vivo and in vitro.

New
Liu et al., Shanghai, China. In Development, Jan 2016
Here, we identify a protein-protein interaction between Nibbler (Nbr), a 3'-to-5' exoribonuclease and Piwi, linking Nbr activity with piRNA pathways.
Surprises in the 3'-end: 'U' can decide too!
Review
New
Arraiano et al., Lisbon, Portugal. In Febs J, Sep 2015
Namely, Dis3L2 is a 3'-5' exoribonuclease from the RNase II/RNB family that has been shown to act preferentially on oligo(U)-tailed transcripts.
Functional non-coding RNAs derived from the flavivirus 3' untranslated region.
Review
New
Khromykh et al., Brisbane, Australia. In Virus Res, Sep 2015
In this review we summarize published data from studies with WNV, YFV, DENV, JEV, and MVEV on sfRNA production following incomplete degradation of the viral genomic RNA by the cellular 5'-3' exoribonuclease 1 (XRN1), RNA structural elements involved in stalling XRN1 to generate sfRNA, and functions of sfRNA in modulating cellular mRNA decay and RNAi pathways as well as in modulating anti-viral type I interferon response.
Perspective: The RNA exosome, cytokine gene regulation and links to autoimmunity.
Review
New
Fitzgerald et al., Lyon, France. In Cytokine, Aug 2015
The RNA exosome is a highly conserved exoribonuclease complex that is involved in RNA processing, quality control and turnover regulation.
Exome sequencing links mutations in PARN and RTEL1 with familial pulmonary fibrosis and telomere shortening.
New
Impact
Garcia et al., Dallas, United States. In Nat Genet, May 2015
Gene burden analysis comparing 78 European cases and 2,816 controls implicated PARN, an exoribonuclease with no previous connection to telomere biology or disease, with five new heterozygous damaging mutations in unrelated cases and none in controls (P = 1.3 × 10(-8)); mutations were shared by all affected relatives (odds in favor of linkage = 4,096:1).

Review
Newbury et al., Brighton, United Kingdom. In Biomolecules, 2014
DIS3 is a conserved exoribonuclease and catalytic subunit of the exosome, a protein complex involved in the 3' to 5' degradation and processing of both nuclear and cytoplasmic RNA species.

Conti et al., München, Germany. In Cell, 2013
Biochemical data suggest that the Ski complex can thread RNAs directly to the exosome, coupling the helicase and the exoribonuclease through a continuous RNA channel.
