Global Characterization of XRN 5′-3′ Exoribonucleases and Their Responses to Environmental Stresses in Plants [PDF]
The XRN family of 5′-3′ Exoribonucleases is functionally conserved in eukaryotic organisms. However, the molecular evolution of XRN proteins in plants and their functions in plant response to environment stresses remain largely unexplored. In this study,

Crystallographic Studies of Bacterial Exoribonucleases [PDF]
INTRODUCTION. Ribonucleases (RNases) play a central role in all cellular RNA processes. These processes include mRNA degradation, and maturation and turnover of stable RNAs, which are vital for the proper functioning of all cells. E. coli has served as a model system for understanding the role of ribonucleases in RNA metabolism, and eight distinct ...

Exoribonucleases as modulators of virulence in pathogenic bacteria [PDF]
Pathogenic bacteria are responsible for severe diseases worldwide. RNA stability is a major player controlling the expression of virulence factors. Ribonucleases (RNases) are the enzymes responsible for the maturation and degradation of RNA molecules (Arraiano et al., 2010; Silva et al., 2011).

Cap-Independent Circular mRNA Translation Efficiency
Recently, the mRNA platform has become the method of choice in vaccine development to find new ways to fight infectious diseases. However, this approach has shortcomings, namely that mRNA vaccines require special storage conditions, which makes them less

Real-time fluorescence detection of exoribonucleases [PDF]
The identification of RNases or RNase effectors is a continuous challenge, particularly given the current importance of RNAs in the control of genome expression. Here, we show that a fluorogenic RNA–DNA hybrid is a powerful tool for a real-time fluorescence detection and assay of exoribonucleases (RT-FeDEx).

Bacterial RNA degradation is typically initiated by endoribonucleases and followed by exoribonucleases. Here the authors report the targetome of endoRNase Y in Streptococcus pyogenes, revealing the interplay between RNase Y and 3′-to-5′ exoribonuclease ...

The Bacillus subtilis genome encodes four 3′ exoribonucleases: polynucleotide phosphorylase (PNPase), RNase R, RNase PH, and YhaM. Previous work showed that PNPase, encoded by the pnpA gene, is the major 3′ exonuclease involved in mRNA turnover; in a ...

Summary: Processive exoribonucleases are executors of RNA decay. In humans, their physical but not functional interactions were thoughtfully investigated. Here we have screened cells deficient in DIS3, XRN2, EXOSC10, DIS3L, and DIS3L2 with a custom siRNA

A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation [PDF]
Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) and are formed when the enzyme ...

Shared properties and singularities of exoribonuclease-resistant RNAs in viruses
What viral RNA genomes lack in size, they make up for in intricacy. Elaborate RNA structures embedded in viral genomes can hijack essential cellular mechanisms aiding virus propagation.
