Application

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.

Almost all RNAs can fold to form extensive base-paired secondary structures. Many of these structures then modulate numerous fundamental elements of gene expression. Deducing these structure-function relationships requires that it be possible to predict RNA secondary structures accurately. However, RNA

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

mRNAs can fold into complex structures that regulate gene expression. Resolving such structures de novo has remained challenging and has limited our understanding of the prevalence and functions of mRNA structure. We use SHAPE-MaP experiments in living E. coli cells to

Higher-order structure influences critical functions in nearly all noncoding and coding RNAs. Most single-nucleotide resolution RNA structure determination technologies cannot be used to analyze RNA from scarce biological samples, like viral genomes.
