Landscape of functional interactions of human processive ribonucleases revealed by high-throughput siRNA screenings

open access: yesiScience, 2021
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

Exoribonuclease RNase R protects Antarctic Pseudomonas syringae Lz4W from DNA damage and oxidative stress. [PDF]

open access: yesAppl Environ Microbiol, 2023
Bacterial exoribonucleases play a crucial role in RNA maturation, degradation, quality control, and turnover. In this study, we have uncovered a previously unknown role of 3-5 exoribonuclease RNase R of Pseudomonas syringae Lz4W in DNA damage and ...

Immunosuppressive arenaviral exoribonuclease

open access: yesOncotarget, 2015
Arenaviruses cause up to 500,000 zoonotic infections per year in endemic areas of Africa and South America and can lead to severe and lethal hemorrhagic fever (HF) symptoms [1]. Currently, there is no specific antiviral drug or vaccine available for the treatment of these infections, with the exception of the Candid #1 vaccine that has successfully ...

The roles of the exoribonucleases DIS3L2 and XRN1 in human disease [PDF]

open access: yesBiochemical Society Transactions, 2016
RNA degradation is a vital post-transcriptional process which ensures that transcripts are maintained at the correct level within the cell. DIS3L2 and XRN1 are conserved exoribonucleases that are critical for the degradation of cytoplasmic RNAs. Although the molecular mechanisms of RNA degradation by DIS3L2 and XRN1 have been well studied, less is ...

Localization of components of the RNA-degrading machine in Bacillus subtilis

open access: yesFrontiers in Microbiology, 2016
In bacteria, the control of mRNA stability is crucial to allow rapid adaptation to changing conditions. In most bacteria, RNA degradation is catalyzed by the RNA degradosome, a protein complex composed of endo- and exoribonucleases, RNA helicases and ...

Depletion of trypanosome CTR9 leads to gene expression defects. [PDF]

open access: yesPLoS ONE, 2012
The Paf complex of Opisthokonts and plants contains at least five subunits: Paf1, Cdc73, Rtf1, Ctr9, and Leo1. Mutations in, or loss of Paf complex subunits have been shown to cause defects in histone modification, mRNA polyadenylation, and transcription

Burning the Candle at Both Ends: Have Exoribonucleases Driven Divergence of Regulatory RNA Mechanisms in Bacteria?

open access: yesmBio, 2021
Regulatory RNAs have emerged as ubiquitous gene regulators in all bacterial species studied to date. The combination of sequence-specific RNA interactions and malleable RNA structure has allowed regulatory RNA to adopt different mechanisms of gene ...

Moonlighting in Bacillus subtilis: The Small Proteins SR1P and SR7P Regulate the Moonlighting Activity of Glyceraldehyde 3-Phosphate Dehydrogenase A (GapA) and Enolase in RNA Degradation

open access: yesMicroorganisms, 2021
Moonlighting proteins are proteins with more than one function. During the past 25 years, they have been found to be rather widespread in bacteria. In Bacillus subtilis, moonlighting has been disclosed to occur via DNA, protein or RNA binding or protein ...

Purification of eukaryotic exoribonucleases following heterologous expression in bacteria and analysis of their biochemical properties by in vitro enzymatic assays [PDF]

open access: yes, 2014
Exoribonucleases-among the other RNases-play a crucial role in the regulation of different aspects of RNA metabolism in the eukaryotic cell. To fully understand the exact mechanism of activity exhibited by such enzymes, it is crucial to determine their ...

Identification of Ribonuclease Inhibitors for the Control of Pathogenic Bacteria. [PDF]

open access: yesInt J Mol Sci
Bacteria are known to be constantly adapting to become resistant to antibiotics. Currently, efficient antibacterial compounds are still available; however, it is only a matter of time until these compounds also become inefficient.
