Exoribonuclease superfamilies: structural analysis and phylogenetic distribution

Nucleic Acids Research, 2001
Exoribonucleases play an important role in all aspects of RNA metabolism. Biochemical and genetic analyses in recent years have identified many new RNases and it is now clear that a single cell can contain multiple enzymes of this class. Here, we analyze the structure and phylogenetic distribution of the known exoribonucleases.

Suppression of Viral RNA Recombination by a Host Exoribonuclease [PDF]

Journal of Virology, 2006
ABSTRACT RNA viruses of humans, animals, and plants evolve rapidly due to mutations and RNA recombination. A previous genome-wide screen in Saccharomyces cerevisiae , a model host, identified five host genes, including XRN1 , encoding a 5′-3′ exoribonuclease, whose absence led to an

Regulation of cytoplasmic RNA stability: lessons from drosophila [PDF]

, 2018
The process of RNA degradation is a critical level of regulation contributing to the control of gene expression. In the last two decades a number of studies have shown the specific and targeted nature of RNA decay and its importance in maintaining ...

Modulation of SAL retrograde signalling promotes yield and water productivity responses in dynamic field environments

New Phytologist, Volume 249, Issue 3, Page 1219-1233, February 2026.
Summary Chloroplast‐to‐nucleus retrograde signalling enables rapid stress responses in plants, but whether these signals accumulate to affect crop performance across entire growing seasons under field conditions remains unknown. We generated wheat mutants with targeted deletions in specific SAL gene copies from two distinct homeologous groups (TaSAL1 ...

Cutoff Suppresses RNA Polymerase II Termination to Ensure Expression of piRNA Precursors [PDF]

, 2016
Small non-coding RNAs called piRNAs serve as guides for an adaptable immune system that represses transposable elements in germ cells of Metazoa. In Drosophila the RDC complex, composed of Rhino, Deadlock and Cutoff (Cuff) bind chromatin of dual-strand ...

Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

Advanced Science, Volume 13, Issue 3, 14 January 2026.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...

Selective 2′-Hydroxyl Acylation Analyzed by Protection from Exoribonuclease [PDF]

Journal of the American Chemical Society, 2010
Selective 2′-hydroxyl acylation analyzed by primer extension (SHAPE) is a powerful approach for characterizing RNA structure and dynamics at single-nucleotide resolution. However, SHAPE technology is limited, sometimes severely, because primer extension detection obscures structural information for ~15 nts at the 5′ end and 40–60 nts at the 3′ end of ...

The 5′ Cap Epitranscriptome and Beyond: Natural and Engineered 5′ Cap Modifications for Optimizing mRNA Therapeutics and Functional Studies

ChemMedChem, Volume 21, Issue 2, January 2026.
5′ Cap modifications can be introduced via enzymes or chemical synthesis. Natural and non‐natural 5′ cap structures affect mRNA properties, including translation (T), stability (S), and/or immunogenicity (I). Eukaryotic mRNAs made by in vitro transcription have emerged as medical modalities for vaccination and protein replacement therapy. The 5′ cap is

The ApaH-like phosphatase TbALPH1 is the major mRNA decapping enzyme of trypanosomes. [PDF]

PLoS Pathogens, 2017
5'-3' decay is the major mRNA decay pathway in many eukaryotes, including trypanosomes. After deadenylation, mRNAs are decapped by the nudix hydrolase DCP2 of the decapping complex and finally degraded by the 5'-3' exoribonuclease. Uniquely, trypanosomes
