TABLE 1.

High-throughput methods for site-specific mapping of Nm sites in RNA

Method Approach Stoichiometry Applications
RiboMeth-seq (Marchand et al. 2016) Alkaline hydrolysis Absolute rRNA, tRNA, snRNA
RibOxi-seq (Zhu et al. 2017) Periodate oxidation No rRNA
Nm-seq (Dai et al. 2017) Periodate oxidation No rRNA, mRNA, miRNA, piRNA
2OMe-seq (Incarnato et al. 2017) RT at low [dNTP] Relative rRNA
MeTH-seq (Bartoli et al. 2018) RT at low [Mg] No mRNA
Nm-Mut-seq (Chen et al. 2023) Engineered RTase Relative rRNA, mRNA
NJU-seq (Tang et al. 2024) MgR cleavage Relative rRNA, mRNA
  • (MgR) Mycoplasma genitalium RNase R; (RT) reverse transcription; (dNTP) deoxynucleotide triphosphate concentration; (Mg) magnesium concentration; (RTase) reverse transcriptase.
