要旨

RNA editing by adenosine deamination is a form of epigenetic control of gene expression wherein the ADAR enzymes convert adenosine to inosine in RNA often changing the meaning of codons. The pre-mRNA for the 2c subtype of serotonin receptor (5-HT2cR) is shown here to support small molecule binding near known editing sites. Furthermore, a helix-threading peptide binds this site and inhibits the in vitro reaction of ADAR2 in an RNA-substrate selective manner. This is the first example of substrate-selective inhibition of editing by an RNA-binding small molecule and sets the stage for the development of new reagents capable of controlling gene function through manipulation of mRNA editing.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
