1-Methyl-7-nitroisatoic anhydride (1M7) is used as an in vivo SHAPE-MaP reagent for live cell RNA structure analysis at single nucleotide resolution. SHAPE -- or selective 2′-hydroxyl acylation analyzed by primer extension -- uses small, electrophilic chemical probes such as 1M7 to react with the 2′-hydroxyl group and provides insight to RNA structure. When combined with mutational profiling (MaP), quantitative nucleotide measurements are possible for entire transciptomes. Together, these methods deepen the understanding of RNA interactions and regions that may be exploited for design of RNA-targeting small-molecule drugs.

RNA SHAPE chemistry yields quantitative, single-nucleotide resolution structural information based on the reaction of the 2'-hydroxyl group of conformationally flexible nucleotides with electrophilic SHAPE reagents. However, SHAPE technology has been limited by the requirement that sites of RNA modification be

Riboswitches are non-coding RNAs that control gene expression by sensing small molecules through changes in secondary structure. While secondary structure and ligand interactions are thought to control switching, the exact mechanism of control is unknown. Using a novel two-piece assay

SHAPE-MaP is unique among RNA structure probing strategies in that it both measures flexibility at single-nucleotide resolution and quantifies the uncertainties in these measurements. We report a straightforward analytical framework that incorporates these uncertainties to allow detection of RNA structural
