Epitranscriptomic RNA modifications can regulate RNA activity, however there remains a major gap in our understanding of the RNA chemistry present in biological systems. Here, we develop RNA-mediated activity-based protein profiling (RNABPP), a chemoproteomic strategy relying upon metabolic RNA labeling, mRNA interactome capture, and quantitative proteomics, to investigate RNA-modifying enzymes in human cells. RNABPP with 5-fluoropyrimidines allowed us to profile 5-methylcytidine (m5C) and 5-methyluridine (m5U) methyltransferases. Further, we uncover a novel mechanism-based crosslink between 5-fluorouridine-modified RNA and the dihydrouridine synthase homolog DUS3L. We investigate the mechanism of crosslinking and use quantitative nucleoside LC-MS/MS analysis and 5-fluorouridine-based crosslinking and immunoprecipitation (CLIP) sequencing to map DUS3L-dependent dihydrouridine (DHU) modifications transcriptome-wide. Finally, we show that DUS3L KO cells have compromised protein translation rates and impaired cellular proliferation. Taken together, our work provides a general approach for profiling RNA modifying enzyme activity in living cells and reveals new pathways for epitranscriptomic RNA regulation.
