Reversible and Rapid Transfer-RNA Deactivation as a Mechanism of Translational Repression in Stress

open access: yesPLoS Genetics, 2013
Stress-induced changes of gene expression are crucial for survival of eukaryotic cells. Regulation at the level of translation provides the necessary plasticity for immediate changes of cellular activities and protein levels.

Characterization of three proteins involved in polypeptide chain termination. [PDF]

open access: yes, 1969
Journal ArticleAt each stage of elongation, the growing polypeptide chain is bound to the ribosome-messenger RNA complex through the transfer RNA of the most recently incorporated amino acid residue.

Transfer RNA Post-Transcriptional Processing, Turnover, and Subcellular Dynamics in the Yeast Saccharomyces cerevisiae

open access: yesGenetics, 2013
Transfer RNAs (tRNAs) are essential for protein synthesis. In eukaryotes, tRNA biosynthesis employs a specialized RNA polymerase that generates initial transcripts that must be subsequently altered via a multitude of post-transcriptional steps before the

Asymptotic Enumeration of RNA Structures with Pseudoknots [PDF]

open access: yesarXiv, 2007
In this paper we present the asymptotic enumeration of RNA structures with pseudoknots. We develop a general framework for the computation of exponential growth rate and the sub exponential factors for $k$-noncrossing RNA structures. Our results are based on the generating function for the number of $k$-noncrossing RNA pseudoknot structures, ${\sf S}_k(

Screening Genome Sequences for Known RNA Genes and Motifs [PDF]

open access: yes, 2015
This methods paper presents computational protocols for the identification of non-coding RNA genes or RNA motifs within genomic sequences. An application to bacterial small RNA is proposed.

Predicting Cellular Responses to Novel Drug Perturbations at a Single-Cell Resolution [PDF]

open access: yesarXiv, 2022
Single-cell transcriptomics enabled the study of cellular heterogeneity in response to perturbations at the resolution of individual cells. However, scaling high-throughput screens (HTSs) to measure cellular responses for many drugs remains a challenge due to technical limitations and, more importantly, the cost of such multiplexed experiments.

Structurexplor : a platform for the exploration of structural features of RNA secondary structures [PDF]

open access: yes, 2017
: Summary: Discovering function-related structural features, such as the cloverleaf shape of transfer RNA secondary structures, is essential to understand RNA function.

Structural organization of complexes of transfer RNAs with aminoacyl transfer RNA synthetases

open access: yesNucleic Acids Research, 1977
A variety of experimental data on synthetase-tRNA interactions are examined. Although these data previously had no direct explanation when viewed only in terms of the tRNA cloverleaf diagram, they can be rationalized according to a simple proposal that takes account of the three dimensional structure of tRNA.

Transfer RNA modifications: nature's combinatorial chemistry playground

open access: yesWiley Interdisciplinary Reviews - RNA, 2013
Following synthesis, tRNAs are peppered by numerous chemical modifications which may differentially affect a tRNA's structure and function. Although modifications affecting the business ends of a tRNA are predictably important for cell viability, a ...

Small RNA-based feedforward loop with AND-gate logic regulates extrachromosomal DNA transfer in Salmonella [PDF]

open access: yes, 2015
Horizontal gene transfer via plasmid conjugation is a major driving force in microbial evolution but constitutes a complex process that requires synchronization with the physiological state of the host bacteria.
