表位转录组RNA修饰可以调节RNA活性,然而,我们对生物系统中存在的RNA化学的理解仍然存在重大差距。在这里,我们开发了RNA介导的基于活性的蛋白质分析(RNABPP),一种依赖于代谢RNA标记,mRNA相互作用组捕获和定量蛋白质组学的化学蛋白质组学策略,以研究人类细胞中的RNA修饰酶。使用5-氟嘧啶的RNABPP使我们能够分析5-甲基胞苷(m5 C)和5-甲基尿苷(m5 U)甲基转移酶。此外,我们发现了一种新的机制为基础的5-氟尿苷修饰的RNA和二氢尿苷合酶同系物DUS 3L之间的交联。我们研究了交联机制,并使用定量核苷LC-MS/MS分析和基于5-氟尿苷的交联和免疫沉淀(CLIP)测序来绘制DUS 3L依赖性二氢尿苷(DHU)修饰的转录组范围。最后,我们表明DUS 3L KO细胞具有受损的蛋白质翻译速率和受损的细胞增殖。总之,我们的工作提供了一个通用的方法来分析RNA修饰酶在活细胞中的活性,并揭示了新的途径epitranscriptomic RNA调控。
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.
