Combinatorics of RNA Structures with Pseudoknots [PDF]

Bulletin of Mathematical Biology, 2007
In this paper we derive the generating function of RNA structures with pseudoknots. We enumerate all $k$-noncrossing RNA pseudoknot structures categorized by their maximal sets of mutually intersecting arcs. In addition we enumerate pseudoknot structures over circular RNA. For 3-noncrossing RNA structures and RNA secondary structures we present a novel

It's a loop world – single strands in RNA as structural and functional elements

Biomolecular Concepts, 2011
Unpaired regions in RNA molecules – loops – are centrally involved in defining the characteristic three-dimensional (3D) architecture of RNAs and are of high interest in RNA engineering and design.

RNApolis: Computational Platform for RNA Structure Analysis

Foundations of Computing and Decision Sciences, 2019
In the 1970s, computer scientists began to engage in research in the field of structural biology. The first structural databases, as well as models and methods supporting the analysis of biomolecule structures, started to be created.

RNA Interference by Single- and Double-stranded siRNA With a DNA Extension Containing a 3′ Nuclease-resistant Mini-hairpin Structure [PDF]

, 2013
Selective gene silencing by RNA interference (RNAi) involves double-stranded small interfering RNA (ds siRNA) composed of single-stranded (ss) guide and passenger RNAs.

Domain orientation in the RNA helicase YxiN and the role of conformational changes for RNA unwinding [PDF]

, 2010
The RNA helicase YxiN from Bacillus subtilis is a member of the family of DEAD box proteins. YxiN is able to unwind RNA double strands in an ATP-dependent manner. The ability to catalyse RNA rearrangement is in vivo presumably necessary for the bacterial

An improved method for surface immobilisation of RNA: application to small Non-Coding RNA - mRNA pairing [PDF]

, 2013
Characterisation of RNA and its intermolecular interactions is increasing in importance as the inventory of known RNA functions continues to expand. RNA-RNA interactions are central to post-transcriptional gene regulation mechanisms in bacteria, and the ...

Structural Alignment of Pseudoknotted RNA [PDF]

Journal of Computational Biology, 2006
In this paper, we address the problem of discovering novel non-coding RNA (ncRNA) using primary sequence, and secondary structure conservation, focusing on ncRNA families with pseudoknotted structures. Our main technical result is an efficient algorithm for computing an optimum structural alignment of an RNA sequence against a genomic substring.

A hepatitis C virus cis-acting replication element forms a long-range RNA-RNA interaction with upstream RNA sequences in NS5B [PDF]

, 2008
The genome of hepatitis C virus (HCV) contains cis-acting replication elements (CREs) comprised of RNA stem-loop structures located in both the 5' and 3' non-coding regions (NCR), and in the NS5B coding sequence.

Helix capping in RNA structure. [PDF]

PLoS ONE, 2014
Helices are an essential element in defining the three-dimensional architecture of structured RNAs. While internal basepairs in a canonical helix stack on both sides, the ends of the helix stack on only one side and are exposed to the loop side, thus ...

RNA Secondary Structure Prediction [PDF]

Current Protocols in Nucleic Acid Chemistry, 2000
AbstractDetails for predicting secondary structure of RNA sequences using free energy minimization are given. Protocols present the use of the RNAstructure computer program (for PCs) and the mfold server (for Unix platforms). The minimum free energy structure and a set of suboptimal structures with similar free energies are predicted.
