RNA modification of an RNA modifier prevents self-RNA sensing
PLOS Biology, 2021 A new study in PLOS Biology finds that interferon (IFN)-induced adenosine deaminase acting on RNA 1 (ADAR1) mRNA is N6-methyladenosine (m6A) modified to promote its translation, enabling ADAR1 to modify self-double-stranded RNAs (dsRNAs) generated during the IFN response and preventing activation of the melanoma differentiation-associated protein 5 ...

Nanostructured RNA for RNA Intereference
YAKUGAKU ZASSHI, 2013 RNA interference (RNAi) is a potent and highly specific gene-silencing phenomenon which is initiated or triggered by double-stranded RNAs (dsRNAs). Shortly after the development of RNAi, small interfering RNAs (siRNAs) that are 21 nucleotides in length with a 3' nucleotide overhang were shown to be very effective in mammalian cells.

Cell, 2009 Cellular functions depend on numerous protein-coding and noncoding RNAs and the RNA-binding proteins associated with them, which form ribonucleoprotein complexes (RNPs). Mutations that disrupt either the RNA or protein components of RNPs or the factors required for their assembly can be deleterious. Alternative splicing provides cells with an exquisite

An RNA-dependent RNA polymerase formed by TERT and the RMRP RNA [PDF]
Nature, 2009 Constitutive expression of telomerase in human cells prevents the onset of senescence and crisis by maintaining telomere homeostasis. However, accumulating evidence suggests that the human telomerase reverse transcriptase catalytic subunit (TERT) contributes to cell physiology independently of its ability to elongate telomeres.

Generalized RNA-Directed Recombination of RNA [PDF]
Chemistry & Biology, 2003 RNA strand exchange through phosphor-nucleotidyl transfer reactions is an intrinsic chemistry promoted by group I intron ribozymes. We show here that Tetrahymena and Azoarcus ribozymes can promote RNA oligonucleotide recombination in either two-pot or one-pot schemes. These ribozymes bind one oligonucleotide, cleave following a guide sequence, transfer

RNA Captor: A Tool for RNA Characterization
PLoS ONE, 2011 In the genome era, characterizing the structure and the function of RNA molecules remains a major challenge. Alternative transcripts and non-protein-coding genes are poorly recognized by the current genome-annotation algorithms and efficient tools are needed to isolate the less-abundant or stable RNAs.A universal RNA-tagging method using the T4 RNA ...

RNA tectonics: towards RNA design
Folding and Design, 1996 Our understanding of the structural, folding and catalytic properties of RNA molecules has increased enormously in recent years. The discovery of catalytic RNA molecules by Sidney Altman and Tom Cech, the development of in vitro selection procedures, and the recent crystallizations of hammerhead ribozymes and of a large domain of an autocatalytic group

Dissecting RNA-protein interactions: RNA-RNA recognition by Rop
Cell, 1995 The ColE1 plasmid of E. coli encodes a small RNA-binding protein, Rop, which is involved in the regulation of plasmid copy number. Rop, a 4-helix bundle protein, facilitates sense-antisense RNA pairing by binding to the transiently formed hairpin pairs of RNA I and the complementary RNA II.

Cell, 2009 New roles for RNAs in biology continue to emerge, and a glance at the history of RNAs may prepare molecular biologists for future discoveries about these powerful molecules. A striking new role for RNAs is their widespread involvement in the regulation of numerous genes, suggesting that there is much yet to discover about these amazing cellular ...
