A common problem for researchers working with RNA is to determine the three-dimensional structure of the molecule. However, in the case of RNA much of the final structure is determined by the secondary structure or intra-molecular base-pairing interactions of the molecule. This is shown by the high conservation of base-pair across diverse species. One of the first attempts to predict RNA secondary structure was made by Ruth Nussinov and co-workers who used dynamic programming method for maximising the number of base-pairs [1]. However, there are several issues with this approach, most importantly the solution is not unique. Nussinov et al published an adaptation of their approach to use a simple nearest-neighbour energy model in 1980 [2]. Michael Zuker and Patrick Stiegler in 1981 proposed using a slightly refined dynamic programming approach that models nearest neighbour energy interactions that directly incorporates stacking into the prediction [3]. The energies that are minimized by the ...
This chapter relates the intricate architecture of the L11-RNA complex to previous studies that delineated crucial features of the RNA tertiary structure and protein-RNA interface. In describing the structure, it is interesting to note how conservation and variation of different nucleotides and amino acids serve as a guide to critical features of the complex, and the authors use the extreme conservation of some bases to speculate about functional surfaces of the rRNA domain. Lastly, the chapter discusses the possibility that the functional role of L11-C76 is to promote a correct RNA tertiary fold. Relatively few RNA structures that have noncanonical interactions have been determined at atomic resolution, and of these only tRNA and the P4-P6 domain of group I intron have extensive tertiary structure. From nuclear magnetic resonance (NMR) studies of the free L11 RNA binding domain (L11-C76), it was known that the protein folds into three α-helices that are superimposable on the α-helices of the
There is a significant need for new therapeutic approaches to combat diseases such as cancer and viral infections. Using RNA as a therapeutic modality brings to bear an entirely new approach, which not only allows for the construction of uniform scaffolds for attachment of functional entities, but also permits the use of all the different types of functionalities that are inherent in natural RNAs. New research demonstrates that multifunctional RNA nanoparticles with a nanoring design allow the use of different types of functionalities inherent in natural RNAs.

Eternabot 2.0 is a set of rules developed by the Eterna project (eternagame.org) to predict sequences for a target RNA secondary structure
The RNA shapes studio comprises four RNA secondary structure prediction tools, which make heavy use of shape abstraction. An abstract shape is a mathematically well defined coarse grained view of an RNA structure, supporting the user to focus only on "interesting" structural features. RNAshapes and pKiss operate on single sequence inputs. Their counterparts RNAalishapes and pAliKiss take an multiple sequence alignment as input. RNAshapes and RNAalishapes predict purely nested secondary structures. pKiss and pAliKiss additionally consider H-type pseudoknots and kissing hairpins. KnotInFrame - KnotInFrame is a pipeline to predict ribosomal -1 frameshift sites with a simple pseudoknot as secondary structure in DNA and RNA sequences.. pAliKiss - pAliKiss is a tool for secondary structure prediction including kissing hairpin motifs.. pKiss - pKiss is a tool for secondary structure prediction including kissing hairpin motifs.. pknotsRG - RNA folding and thermodynamic matching RapidShapes - Computes a ...

By the analysis of thermodynamic RNA secondary structure predictions, we previously obtained evidence for evolutionarily conserved large-scale ordering of RNA virus genomes (P. Simmonds, A. Tuplin, and D.J. Evans, RNA 10: 1337-1351, 2004). Genome-scale ordered RNA structure (GORS) was widely distributed in many animal and plant viruses, much greater in extent than RNA structures required for viral translation or replication, but in mammalian viruses was associated with host persistence. To substantiate the existence of large-scale RNA structure differences between viruses, a large set of alignments of mammalian RNA viruses and rRNA sequences as controls were examined by thermodynamic methods (to calculate minimum free energy differences) and by algorithmically independent RNAz and Pfold methods. These methods produced generally concordant results and identified substantial differences in the degrees of evolutionarily conserved, sequence order-dependent RNA secondary structure between virus ...

The PreQ1-I riboswitch is a cis-acting element identified in bacteria which regulates expression of genes involved in biosynthesis of the nucleoside queuosine (Q) from GTP. PreQ1 (pre-queuosine1) is an intermediate in the queuosine pathway, and preQ1 riboswitch, as a type of riboswitch, is an RNA element that binds preQ1. The preQ1 riboswitch is distinguished by its unusually small aptamer, compared to other riboswitches. Its atomic-resolution three-dimensional structure has been determined, with the PDB ID 2L1V. Three subcategories of the PreQ1 riboswitch exist: preQ1-I, preQ1-II, and preQ1-III. PreQ1-I has a distinctly small aptamer, ranging from 25 to 45 nucleotides long, compared to the structures of PreQ1-II riboswitch and preQ1-III riboswitch. PreQ1-II riboswitch, only found in Lactobacillales, has a larger and more complex consensus sequence and structure than preQ1-I riboswitch, with an average of 58 nucleotides composing its aptamer, which forms as many as five base-paired ...

We investigate the empirical complexity of the RNA secondary structure design problem, that is, the scaling of the typical difficulty of the design task for various classes of RNA structures as the size of the target structure is increased. The purpose of this work is to understand better the factors that make RNA structures hard to design for existing, high-performance algorithms. Such understanding provides the basis for improving the performance of one of the best algorithms for this problem, RNA-SSD, and for characterising its limitations. To gain insights into the practical complexity of the problem, we present a scaling analysis on random and biologically motivated structures using an improved version of the RNA-SSD algorithm, and also the RNAinverse algorithm from the Vienna package. Since primary structure constraints are relevant for designing RNA structures, we also investigate the correlation between the number and the location of the primary structure constraints when designing structures

RNA structure is important for RNA function and regulation, and there is growing interest in determining the RNA structure of many transcripts. Here we provide a detailed protocol for the parallel analysis of RNA structure (PARS) for probing RNA secondary structures genome-wide. In this method, enzymatic footprinting is coupled to high-throughput sequencing to provide secondary structure data for thousands of RNAs simultaneously. The entire experimental protocol takes ∼5 d to complete, and sequencing and data analysis take an additional 6-8 d. PARS was developed using the yeast genome as proof of principle, but its approach should be applicable to probing RNA structures from different transcriptomes and structural dynamics under diverse solution conditions.

The initial version was coded after several unfruitful attempts at finding a RNA secondary structure drawing software to be used inside of a webserver. Indeed, it seemed at the time that most of the webservers dedicated to the secondary structure of RNA offered rather clumsy renderings (Mostly static, cgi-bin generated, PS or PNG files). In 2008, I (Yann Ponty) was unable to find a tool that would be at the same time available, easy to install and still running (SStructView was no longer tolerated by latest Java plugins security policies; RNAMLViews goal was rather to display a projection of the 3D structure, and RNAMovies was more tailored towards animations...). Therefore, I coded a basic software from scratch, initially using a radial layout strategy adopted by the software RNAViz, later to be extended to other classic algorithms such that NAView, a classic Feynman-diagram representation and a linear one, hoping it would be useful to some... VARNA development team was subsequently joined by ...

The known functions of RNA structures have expanded of late, such that RNA is considered a more active player in molecular biology. The presence of RNA secondary structure in a sequence should constrain evolution of its constituent nucleotides because of the requirement to maintain the base-pairing regions in the structure. In a previous work, we found support for this hypothesis in nine molecules from various organisms, the exception being a structure found in a protein-coding region of the HIV-1 genome. In this work, I examine the interaction of constraints imposed by RNA structures and host-induced hypermutation on molecular evolution in HIV-1. I conclude that RNA structures in HIV do evolve via compensatory evolution, but that hypermutation can obscure the expected signal. Since RNAs known roles have increased, so have the methods for identification and prediction of RNA structures in genetic sequence. I use a method adapted for searching in multiple coding regions to identify conserved RNA ...
