Structural and functional studies of the decapping exoribonucleases [PDF]

Acta Crystallographica Section A Foundations and Advances, 2014
Recent studies showed that two homologous yeast proteins, Rai1 and Dxo1, function in a quality control mechanism to clear cells of incompletely 5' end-capped messenger RNAs (mRNAs). Rai1 possesses a novel decapping activity that can remove the entire cap structure dinucleotide from an mRNA.

Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 1973-2000, July 2026.
Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

RISC-interacting clearing 3’- 5’ exoribonucleases (RICEs) degrade uridylated cleavage fragments to maintain functional RISC in Arabidopsis thaliana

eLife, 2017
RNA-induced silencing complex (RISC) is composed of miRNAs and AGO proteins. AGOs use miRNAs as guides to slice target mRNAs to produce truncated 5' and 3' RNA fragments. The 5' cleaved RNA fragments are marked with uridylation for degradation.

The Absence of E. coli Nucleoid‐Associated Protein FIS at Low Temperature Leads to an Adaptation Response That Causes a Shift Towards Genome Compaction in Small Rods

Molecular Microbiology, Volume 126, Issue 1, Page 111-125, July 2026.
Unlike the wild‐type BW25113, the fis null mutant is characterized by biphasic growth at 12°C. During the first phase of growth, the absence of FIS results in the formation of filaments with dispersed nucleoids. During the acclimation phase, the FIS Null Adaptation Response is activated that leads to an increase in cell division and nucleoid ...

Attachment of the RNA degradosome to the bacterial inner cytoplasmic membrane prevents wasteful degradation of rRNA in ribosome assembly intermediates.

PLoS Biology, 2023
RNA processing and degradation shape the transcriptome by generating stable molecules that are necessary for translation (rRNA and tRNA) and by facilitating the turnover of mRNA, which is necessary for the posttranscriptional control of gene expression ...

Investigation of the Relationship Between Ovine Selection Signature DIS3 Like 3′‐5′ Exoribonuclease 2 (DIS3L2) Gene and Weaning Weight and Average Daily Gain Until Weaning in Lambs

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The growing demand for animal products, combined with declining livestock production due to urbanization and climate change, underscores the need for sustainable breeding strategies. In sheep production, liveweight and weight gain until weaning are key economic traits.

Exoribonucleases and their multiple roles in RNA metabolism [PDF]

, 2001
In recent years there has been a dramatic shift in our thinking about ribonucleases (RNases). Although they were once considered to be nonspecific, degradative enzymes, it is now clear that RNases play a central role in every aspect of cellular RNA ...

In vivo 3′-to-5′ exoribonuclease targetomes of Streptococcus pyogenes [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance To cope with harsh environments and cause infection, bacteria need to constantly adjust gene expression. Ribonucleases (RNases) control the abundance of regulatory and protein-coding RNA through degradation and maturation.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

Advanced Science, Volume 13, Issue 27, 13 May 2026.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

PPR Protein BFA2 Is Essential for the Accumulation of the atpH/F Transcript in Chloroplasts

Frontiers in Plant Science, 2019
As a fascinating and complicated nanomotor, chloroplast ATP synthase comprises nine subunits encoded by both the nuclear and plastid genomes. Because of its uneven subunit stoichiometry, biogenesis of ATP synthase and expression of plastid-encoded ATP ...
