Insights into the mechanisms of eukaryotic translation gained with ribosome profiling [PDF]

, 2016
The development of Ribosome Profiling (RiboSeq) has revolutionized functional genomics. RiboSeq is based on capturing and sequencing of the mRNA fragments enclosed within the translating ribosome and it thereby provides a â snapshotâ of ribosome ...

Genetic dissection reveals distinct contributions of the eS31 N‐terminal domain to translational accuracy in Saccharomyces cerevisiae

The FEBS Journal, EarlyView.
The eukaryote‐specific N‐terminal domain (NTD) of eS31 uses two distinct strategies to maintain translation fidelity. During elongation, a positively charged “hotspot” fine‐tunes the selection of incoming aa‐tRNA. During termination, the entire NTD acts as a structural scaffold to ensure the correct positioning of the release factor eRF1.

Metabolic stress promotes stop-codon readthrough and phenotypic heterogeneity

, 2023
Accurate protein synthesis is a tightly controlled biological process with multiple quality control steps safeguarded by aminoacyl-transfer RNA (tRNA) synthetases and the ribosome. Reduced translational accuracy leads to various physiological changes in both prokaryotes and eukaryotes. Termination of translation is signaled by stop codons and catalyzed

A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation [PDF]

, 2019
Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) and are formed when the enzyme ...

Salt Stress Adaptations in Soybean Involve Alterations in Pre‐mRNA Processing

Plant, Cell &Environment, EarlyView.
ABSTRACT Salt stress can seriously affect plant survival. To adapt to salt stress, plants can alter gene expressions and/or pre‐mRNA processing patterns, or both. Previous studies could not comprehensively profile stress‐responsive pre‐mRNA processing patterns due to limitations in traditional sequencing technologies.

New insights into stop codon recognition by eRF1 [PDF]

, 2015
In eukaryotes, translation termination is performed by eRF1, which recognizes stop codons via its N-terminal domain. Many previous studies based on point mutagenesis, cross-linking experiments or eRF1 chimeras have investigated the mechanism by which the

Advances in large DNA fragment assembly for microbial cell factory engineering

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Aminoglycosides and other factors promoting stop codon readthrough in human cells

Comptes Rendus. Biologies, 2006
Enhanced stop codon readthrough is a potential treatment strategy for diseases caused by nonsense mutations. Here, we compare readthrough levels induced by three types of factors: aminoglycoside antibiotics, suppressor tRNAs, and factors decreasing translation termination efficiency.

A single H/ACA small nucleolar RNA mediates tumor suppression downstream of oncogenic RAS. [PDF]

, 2019
Small nucleolar RNAs (snoRNAs) are a diverse group of non-coding RNAs that direct chemical modifications at specific residues on other RNA molecules, primarily on ribosomal RNA (rRNA).

De novo transcriptome assembly reveals sex-specific selection acting on evolving neo-sex chromosomes in Drosophila miranda. [PDF]

, 2014
BackgroundThe Drosophila miranda neo-sex chromosome system is a useful resource for studying recently evolved sex chromosomes. However, the neo-Y genomic assembly is fragmented due to the accumulation of repetitive sequence.
