Large-scale analysis of RNA methylation from Oxford Nanopore direct RNA sequencing

enright1The rapid advance of high-throughput sequencing technologies has lead to the identification of specific post-transcriptional modifications in thousands of transcripts. These are derived for both protein-coding RNAs and other less abundant RNA classes. Biological functions for the vast majority of these modifications remain uncharacterised. However, many are expected to have significant structural impact. For instance, the well characterized N6-methyladenosine (m6A) modification has been shown to flag mRNAs for fast-track processing via m6A induced structural switches. We aim to use large-scale genomics to directly detect RNA modifications in RNAs and to understand their roles and effect.
