Folding thermodynamics of pseudoknotted chain conformations [PDF]
We develop a statistical mechanical framework for the folding thermodynamics of pseudoknotted structures. As applications of the theory, we investigate the folding stability and the free energy landscapes for both the thermal and the mechanical unfolding of pseudoknotted chains.

DiCleavePlus integrates pre‐miRNA sequence and secondary structure information through Transformer‐based feature extraction to predict Dicer cleavage site positions with high accuracy. The model converts Dicer cleavage prediction into a multi‐class task, enabling precise and robust identification of cleavage intervals across human pre‐miRNAs.

Structure-Function Model for Kissing Loop Interactions That Initiate Dimerization of Ty1 RNA
The genomic RNA of the retrotransposon Ty1 is packaged as a dimer into virus-like particles. The 5′ terminus of Ty1 RNA harbors cis-acting sequences required for translation initiation, packaging and initiation of reverse transcription (TIPIRT).

Insights into factorless translational initiation by the tRNA-like pseudoknot domain of a viral IRES. [PDF]
The intergenic region internal ribosome entry site (IGR IRES) of the Dicistroviridae family adopts an overlapping triple pseudoknot structure to directly recruit the 80S ribosome in the absence of initiation factors.

A Graph Grammar for Modelling RNA Folding
We propose a new approach for modelling the process of RNA folding as a graph transformation guided by the global value of free energy. Since the folding process evolves towards a configuration in which the free energy is minimal, the global behaviour ...

Coordination among tertiary base pairs results in an efficient frameshift-stimulating RNA pseudoknot
Frameshifting is an essential process that regulates protein synthesis in many viruses. The ribosome may slip backward when encountering a frameshift motif on the messenger RNA, which usually contains a pseudoknot structure involving tertiary base pair ...
