Epitranscriptomic mapping of RNA modifications at single-nucleotide resolution using rhodamine sequencing (Rho-seq).


ABSTRACT: The recent development of epitranscriptomics revealed a new fundamental layer of gene expression, but the mapping of most RNA modifications remains technically challenging. Here, we describe our protocol for Rho-Seq, which enables the mapping of dihydrouridine RNA modification at single-nucleotide resolution. Rho-Seq relies on specific rhodamine-labeling of a subset of modified nucleotides that hinders reverse transcription. Although Rho-Seq was initially applied to the detection of dihydrouridine, we show here that it is applicable to other modifications including 7-methylguanosine or 4-thiouridine. For complete details on the use and execution of this protocol, please refer to Finet et al. (2022).
