Probing RNA Structure with Dimethyl Sulfate Mutational Profiling with Sequencing <em>In Vitro</em> and in Cells

چکیده

The role of RNA structure in virtually any biological process has become increasingly evident, especially the past decade. However, classical approaches to solving structure, such as crystallography or cryo-EM, have failed keep up with rapidly evolving field and need for high-throughput solutions. Mutational profiling sequencing using dimethyl sulfate (DMS) MaPseq is a sequencing-based approach infer from base's reactivity DMS. DMS methylates N1 nitrogen adenosines N3 cytosines at their Watson-Crick face when base unpaired. Reverse-transcribing modified thermostable group II intron reverse transcriptase (TGIRT-III) leads methylated bases being incorporated mutations into cDNA. When resulting cDNA mapping it back reference transcript, relative mutation rates each are indicative "status" paired Even though reactivities high signal-to-noise ratio both vitro cells, this method sensitive bias handling procedures. To reduce bias, paper provides protocol treatment cells transcribed RNA.

Quantitative dimethyl sulfate mapping for automated RNA secondary structure inference.

For decades, dimethyl sulfate (DMS) mapping has informed manual modeling of RNA structure in vitro and in vivo. Here, we incorporate DMS data into automated secondary structure inference using an energy minimization framework developed for 2'-OH acylation (SHAPE) mapping. On six noncoding RNAs with crystallographic models, DMS-guided modeling achieves overall false negative and false discovery ...

Probing Xist RNA Structure in Cells Using Targeted Structure-Seq

The long non-coding RNA (lncRNA) Xist is a master regulator of X-chromosome inactivation in mammalian cells. Models for how Xist and other lncRNAs function depend on thermodynamically stable secondary and higher-order structures that RNAs can form in the context of a cell. Probing accessible RNA bases can provide data to build models of RNA conformation that provide insight into RNA function, m...
