Predicting RNA-small molecule binding sites by 3D structure [PDF]

arXiv, 2023
The prediction of RNA-small molecule binding sites is crucial for the discovery of effective drugs. Various computational methods have been developed to address this challenge, using information about the structure and sequence of RNA. In this study, we introduce CplxCavity, a combination of a new algorithm and a machine learning model specifically ...

Why double-stranded RNA resists condensation

Nucleic Acids Research, 2014
The addition of small amounts of multivalent cations to solutions containing double-stranded DNA leads to inter-DNA attraction and eventual condensation. Surprisingly, the condensation is suppressed in double-stranded RNA, which carries the same negative

Double-Stranded RNA Attenuates the Barrier Function of Human Pulmonary Artery Endothelial Cells [PDF]

, 2013
Circulating RNA may result from excessive cell damage or acute viral infection and can interact with vascular endothelial cells. Despite the obvious clinical implications associated with the presence of circulating RNA, its pathological effects on ...

An RNA editor, adenosine deaminase acting on double-stranded RNA (ADAR1).

Journal of Interferon and Cytokine Research, 2014
Adenosine deaminase acting on RNA1 (ADAR1) catalyzes the C6 deamination of adenosine (A) to produce inosine (I) in regions of RNA with double-stranded (ds) character. This process is known as A-to-I RNA editing. Alternative promoters drive the expression

IDN1 and IDN2 are required for de novo DNA methylation in Arabidopsis thaliana. [PDF]

, 2009
DNA methylation is an epigenetic mark affecting genes and transposons. Screening for mutants that fail to establish DNA methylation yielded two we termed "involved in de novo" (idn) 1 and 2.

Single-stranded endonuclease activity in the excretory--secretory products of Trichinella spiralis and Trichinella pseudospiralis [PDF]

, 2000
A novel acidic extracellular single-stranded endonuclease was demonstrated for the first time in the excretory-secretory (E-S) products of 2 species of Trichinella. Unlike the double-stranded endonuclease reported earlier, the single-stranded molecule is

Effectiveness of specific RNA-mediated interference through ingested double-stranded RNA in Caenorhabditis elegans

Genome Biology, 2000
BackgroundIn Caenorhabditis elegans, injection of double-stranded RNA (dsRNA) results in the specific inactivation of genes containing homologous sequences, a technique termed RNA-mediated interference (RNAi).

Extensive adenosine-to-inosine editing detected in Alu repeats of antisense RNAs reveals scarcity of sense–antisense duplex formation [PDF]

, 2006
One type of RNA editing converts adenosine residues to inosine in double-stranded regions. Recent transcriptome analysis has revealed that numerous Alu repeats, present within introns and untranslated regions of human transcripts, are subject to this A→I

Comparative analysis of the taxonomic classification criteria for a number of groups of pathogenic DNA and RNA viruses based on genomic data

Вопросы вирусологии
The basis for criteria of the taxonomic classification of DNA and RNA viruses based on data of the genomic sequencing are viewed in this review. The genomic sequences of viruses, which have genome represented by double-stranded DNA (orthopoxviruses as ...

Shapes of interacting RNA complexes [PDF]

arXiv, 2014
Shapes of interacting RNA complexes are studied using a filtration via their topological genus. A shape of an RNA complex is obtained by (iteratively) collapsing stacks and eliminating hairpin loops. This shape-projection preserves the topological core of the RNA complex and for fixed topological genus there are only finitely many such shapes.Our main ...
