The nucleolar protein NOL12 is required for processing of large ribosomal subunit rRNA precursors in Arabidopsis

open access: yesBMC Plant Biology, 2023
Background NOL12 5′-3′ exoribonucleases, conserved among eukaryotes, play important roles in pre-rRNA processing, ribosome assembly and export. The most well-described yeast counterpart, Rrp17, is required for maturation of 5.8 and 25S rRNAs, whereas ...

Circular RNA as a Potential Biomarker for Forensic Age Prediction

open access: yesFrontiers in Genetics, 2022
In forensic science, accurate estimation of the age of a victim or suspect can facilitate the investigators to narrow a search and aid in solving a crime.

Mechanisms of action of cytoplasmic miRNAs. Part 4. Recruitment of the DCP1-DCP2 decapping complex. Mechanisms of final mRNA degradation

open access: yesZdorovʹe Rebenka, 2022
This scientific review deals with the mechanisms of action of cytoplasmic microRNAs, namely post-transcriptional silencing: recruitment of the DCP1-DCP2 decapping complex and disruption of the interaction of mRNA with ribosomes.

Supporting Role for GTPase Rab27a in Hepatitis C Virus RNA Replication through a Novel miR-122-Mediated Effect. [PDF]

open access: yesPLoS Pathogens, 2015
The small GTPase Rab27a has been shown to control membrane trafficking and microvesicle transport pathways, in particular the secretion of exosomes. In the liver, high expression of Rab27a correlates with the development of hepatocellular carcinoma.

A novel fry1 allele reveals the existence of a mutant phenotype unrelated to 5'->3' exoribonuclease (XRN) activities in Arabidopsis thaliana roots. [PDF]

open access: yesPLoS ONE, 2011
Mutations in the FRY1/SAL1 Arabidopsis locus are highly pleiotropic, affecting drought tolerance, leaf shape and root growth. FRY1 encodes a nucleotide phosphatase that in vitro has inositol polyphosphate 1-phosphatase and 3',(2'),5'-bisphosphate ...

Substrate Recognition and Catalysis by the Exoribonuclease RNase R [PDF]

open access: yesJournal of Biological Chemistry, 2006
RNase R is a processive, 3' to 5' hydrolytic exoribonuclease that together with polynucleotide phosphorylase plays an important role in the degradation of structured RNAs. However, RNase R differs from other exoribonucleases in that it can by itself degrade RNAs with extensive secondary structure provided that a single-stranded 3' overhang is present ...

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

Molecular Interplay of PARN and Telomerase: Tail Modifiers and Disease Implications

open access: yesWIREs RNA, Volume 17, Issue 4, July/August 2026.
Schematic representation of the molecular interplay between PARN, telomerase‐associated, and the involvement of p53 in regulating telomere maintenance and genome stability. The top panel shows how normal PARN levels are involved in regulating p53 levels and balanced telomerase activity through their regulatory interaction with TERC and TERRA, thus ...

The role of individual exoribonucleases in processing at the 3' end of Escherichia coli tRNA precursors [PDF]

open access: yes, 1994
We have used an in vitro Escherichia coli tRNA processing system to investigate the specific role of individual exoribonucleases in the 3' maturation of tRNA precursors.

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

open access: yes, 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 which are critical for the degradation of cytoplasmic RNAs ...
