RNA under Tension: Folding Landscapes, Kinetic Partitioning Mechanism, and Molecular Tensegrity

open access: yes, 2012
Non-coding RNA sequences play a great role in controlling a number of cellular functions, thus raising the need to understand their complex conformational dynamics in quantitative detail.

RNA catalysis in model protocell vesicles. [PDF]

open access: yes, 2005
We are engaged in a long-term effort to synthesize chemical systems capable of Darwinian evolution, based on the encapsulation of self-replicating nucleic acids in self-replicating membrane vesicles.

A Modified Cas9 Scaffold Allows Extension of the Virus‐Induced Gene Editing Technology to the Large Potyvirus Genus

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant viruses are recognized as rapid and effective vectors to deliver CRISPR‐Cas reaction components into plants, a strategy termed virus‐induced gene editing (VIGE). However, VIGE is limited by the host range of the viral vectors. Development of new viral vectors to target a broad range of plant species will potentially enable the delivery ...

A structural analysis of in vitro catalytic activities of hammerhead ribozymes

open access: yesBMC Bioinformatics, 2007
Background Ribozymes are small catalytic RNAs that possess the dual functions of sequence-specific RNA recognition and site-specific cleavage. Trans-cleaving ribozymes can inhibit translation of genes at the messenger RNA (mRNA) level in both eukaryotic ...

Protein design and RNA design: Perspectives

open access: yesQuantitative Biology, Volume 14, Issue 2, June 2026.
Abstract Advances in deep learning and generative modeling have transformed the landscape of protein and RNA design, enabling rapid and precise creation of novel biomolecules with tailored structures and functions. In protein design, generative deep learning frameworks now support backbone generation, sequence optimization, and joint sequence–structure

A recombinase-activated ribozyme to knock down endogenous gene expression in zebrafish.

open access: yesPLoS Genetics
Precise regulation of gene expression is essential to understand a wide range of biological processes. Control over gene expression can be achieved using site-directed recombinases and endonucleases whose efficiency is variable and dependent on the ...

Phylogeny of conserved adenines in linkers of Group-I introns [PDF]

open access: yes, 2009
We have analyzed the linkers in group-I introns, a characteristic region that is crucial to the folding and splicing process of the folded RNA, in seventy sequences spreading across r-RNA, t-RNA and organelle genes from various organisms including algae,

CRISPR/Cas9 Genome Engineering in Non‐Conventional Oleaginous Yeasts: Applications, Challenges, and Prospects

open access: yesYeast, Volume 43, Issue 3, Page 77-88, May 2026.
ABSTRACT Given the biotechnological potential of yeast‐derived oils for oleochemical production, genes encoding lipid metabolism enzymes are key targets for metabolic engineering. Genetic engineering tools such as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9, Transcription Activator‐Like Effector Nucleases (TALENs), Zinc ...

The structure and catalytic mechanism of a pseudoknot-containing hammerhead ribozyme

open access: yesNature Communications
We have determined the crystal structure of a pseudoknot (PK)-containing hammerhead ribozyme that closely resembles the pistol ribozyme, with essentially identical secondary structure and connectivity. The activity is more sensitive to deletion of the G8

SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

open access: yesThe FEBS Journal, Volume 293, Issue 9, Page 2579-2598, May 2026.
The SARS‐CoV‐2 nucleocapsid (N) protein is not only the specific viral RNA packaging protein, but also acts as an RNA chaperone, facilitating RNA folding. We show that it facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone.
