Defective Processing of Cytoplasmic and Chloroplast Ribosomal RNA in the Absence of Arabidopsis DXO1

open access: yesPlant, Cell &Environment, Volume 48, Issue 6, Page 4227-4244, June 2025.
ABSTRACT Decapping 5′‐3′ exoribonucleases from the DXO/Rai1 family are highly conserved among eukaryotes and exhibit diverse enzymatic activities depending on the organism. The biochemical and structural properties of the plant DXO1 differ from the yeast and animal counterparts, which is reflected in the in vivo functions of this enzyme.

Post-transcriptional control by bacteriophage T4: mRNA decay and inhibition of translation initiation [PDF]

open access: yes, 2010
Over 50 years of biological research with bacteriophage T4 includes notable discoveries in post-transcriptional control, including the genetic code, mRNA, and tRNA; the very foundations of molecular biology.

CRISPRmap: an automated classification of repeat conservation in prokaryotic adaptive immune systems

open access: yesNucleic Acids Research, 2013
Central to Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-Cas systems are repeated RNA sequences that serve as Cas-protein–binding templates.

Purification and properties of a novel pyrimidine-specific endoribonuclease termed endoribonuclease VII from calf thymus that is modulated by polyadenylate.

open access: yesJournal of Biological Chemistry, 1983
Endoribonuclease VII, a novel endoribonuclease from calf thymus, was identified and purified by us. The purified enzyme has Mr = 74,000; its homogeneity was checked by analysis in polyacrylamide gels (both in the presence and in the absence of sodium dodecyl sulfate). The nuclease cleaves poly(U) and poly(C) while other single-stranded homopolyribo- as

Cell cycle-dependent translocation of PRC1 on the spindle by Kif4 is essential for midzone formation and cytokinesis.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2005
The spindle midzone, a conspicuous network of antiparallel interdigitating nonkinetochore microtubules between separating chromosomes, plays a crucial role in regulating the initiation and completion of cytokinesis.

Fragmentation of tRNA in Phytophthora infestans asexual life cycle stages and during host plant infection [PDF]

open access: yes, 2014
The oomycete Phytophthora infestans possesses active RNA silencing pathways, which presumably enable this plant pathogen to control the large numbers of transposable elements present in its 240 Mb genome.

RNA/aTNA chimeras: RNAi effects and nucleases resistance of single and double stranded RNAs [PDF]

open access: yes, 2014
The RNA interference pathway (RNAi) is a specific and powerful biological process, triggered by small non-coding RNA molecules and involved in gene expression regulation. In this work, we explored the possibility of increasing the biological stability of

Toxins of Prokaryotic Toxin-Antitoxin Systems with Sequence-Specific Endoribonuclease Activity

open access: yesToxins, 2017
Protein translation is the most common target of toxin-antitoxin system (TA) toxins. Sequence-specific endoribonucleases digest RNA in a sequence-specific manner, thereby blocking translation.

Glioblastoma invasion and cooption depend on IRE1α endoribonuclease activity

open access: yesOncotarget, 2015
IRE1α is an endoplasmic reticulum (ER)-resident transmembrane signaling protein and a cellular stress sensor. The protein harbors a cytosolic dual kinase/endoribonuclease activity required for adaptive responses to micro-environmental changes. In an orthotopic xenograft model of human glioma, invalidation of IRE1α RNase or/and kinase activities ...
