A dynamic RNA loop in an IRES affects multiple steps of elongation factor-mediated translation initiation

open access: yeseLife, 2015
Internal ribosome entry sites (IRESs) are powerful model systems to understand how the translation machinery can be manipulated by structured RNAs and for exploring inherent features of ribosome function.

Aptamer Engineering: Strategies for Discovering Functional Nucleic Acids for Next‐Generation Diagnostics and Biosensing

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

A bacterial riboswitch class for the thiamin precursor HMP-PP employs a terminator-embedded aptamer

open access: yeseLife, 2019
We recently implemented a bioinformatics pipeline that can uncover novel, but rare, riboswitch candidates as well as other noncoding RNA structures in bacteria.

Small synthetic molecule-stabilized RNA pseudoknot as an activator for –1 ribosomal frameshifting

open access: yesNucleic Acids Research, 2018
Programmed –1 ribosomal frameshifting (−1PRF) is a recoding mechanism to make alternative proteins from a single mRNA transcript. −1PRF is stimulated by cis-acting signals in mRNA, a seven-nucleotide slippery sequence and a downstream secondary structure

Structure Modeling Protocols for Protein Multimer and RNA in CASP16 With Enhanced MSAs, Model Ranking, and Deep Learning

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 1, Page 167-182, January 2026.
ABSTRACT We present the methods and results of our protein complex and RNA structure predictions at CASP16. Our approach integrated multiple state‐of‐the‐art deep learning models with a consensus‐based scoring method. To enhance the depth of multiple sequence alignments (MSAs), we employed a large metagenomic sequence database.

Pseudoknots in RNA folding landscapes

open access: yesBioinformatics, 2015
Abstract Motivation: The function of an RNA molecule is not only linked to its native structure, which is usually taken to be the ground state of its folding landscape, but also in many cases crucially depends on the details of the folding pathways such as stable folding intermediates or the timing of the folding process itself. To model

Topology of RNA-RNA interaction structures [PDF]

open access: yes, 2011
The topological filtration of interacting RNA complexes is studied and the role is analyzed of certain diagrams called irreducible shadows, which form suitable building blocks for more general structures.

Functional Relevance of CASP16 Nucleic Acid Predictions as Evaluated by Structure Providers

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 1, Page 51-78, January 2026.
ABSTRACT Accurate biomolecular structure prediction enables the prediction of mutational effects, the speculation of function based on predicted structural homology, the analysis of ligand binding modes, experimental model building, and many other applications.

Theoretical Search for RNA Folding Nuclei

open access: yesEntropy, 2015
The functions of RNA molecules are defined by their spatial structure, whose folding is regulated by numerous factors making RNA very similar to proteins.
