2D projections of RNA folding landscapes 

German conference on bioinformatics 2009 Lorenz, Rony; Flamm, Christoph; Hofacker, Ivo L.
The analysis of RNA folding landscapes yields insights into the kinetic folding behavior not available from classical structure prediction methods. This is especially important for multi-stable RNAs whose function is related to structural changes, as in the case of riboswitches. However, exact methods such as barrier ...

RNAplex: a fast and flexible RNA-RNA interaction search tool 

German conference on bioinformatics – GCB 2007 Tafer, Hakim; Hofacker, Ivo L.
Regulatory RNAs often unfold their action via RNA-RNA interaction. Transcriptional gene silencing by means of siRNAs and miRNA as well as snoRNA directed RNA editing rely on this mechanism. ncRNA regulation in bacteria is mainly based upon RNA duplex formation. Finding putative target sites for newly discovered ncR-NAs ...

RNALfoldz: efficient prediction of thermodynamically stable, local secondary structures 

German Conference on Bioinformatics 2010 Gruber, Andreas R.; Bernhart, Stephan H.; Zhou, You; Hofacker, Ivo L.
The search for local RNA secondary structures and the annotation of unusually stable folding regions in genomic sequences are two well motivated bioinformatic problems. In this contribution we introduce RNALfoldz an efficient solution two tackle both tasks. It is an extension of the RNALfold algorithm augmented by support ...

Comparative analysis of cyclic sequences: Viroids and other small circular RNAs 

German Conference on Bioinformatics Mosig, Axel; Hofacker, Ivo L.; Stadler, Peter F.
The analysis of small circular sequences requires specialized tools. While the differences between linear and circular sequences can be neglected in the case of long molecules such as bacterial genomes since in practice all analysis is performed in sequence windows, this is not true for viroids and related sequences which ...

Conserved RNA pseudoknots 

German Conference on Bioinformatics 2004, GCB 2004 Thurner, Caroline; Hofacker, Ivo L.; Stadler, Peter F.
Pseudoknots are essential for the functioning of many small RNA molecules. In addition, viral RNAs often exhibit pseudoknots that are required at various stages of the viral life-cycle. Techniques for detecting evolutionarily conserved, and hence most likely functional RNA pseudoknots, are therefore of interest. Here we ...

Thermodynamics of RNA-RNA binding 

German Conference on Bioinformatics 2005 (GCB 2005) Mückstein, Ulrike; Tafer, Hakim; Hackermüller, Jörg; Bernhart, Stephan H.; Stadler, Peter F.; Hofacker, Ivo L.
We present an extension of the standard partition function approach to RNA secondary structures that computes the probabilities Pu[i, j] that a sequence interval [i, j] is unpaired. Comparison with experimental data shows that Pu[i, j] can be applied as a significant determinant of local target site accessibility for RNA ...

Memory efficient folding algorithms for circular RNA secondary structures 

German Conference on Bioinformatics 2005 (GCB 2005) Hofacker, Ivo L.; Stadler, Peter F.
A small class of RNA molecules, in particular the tiny genomes of viroids, are circular. Yet most structure prediction algorithms handle only linear RNAs. The most straightforward approach is to compute circular structures from "internal" and "external" substructures separated by a base pair. This is incompatible, however, ...
