Abstract:
Every chemical group that is added to any one of the canonical ribonucleotides in a transcript would create a specific RNA modification. Currently, 170+ RNA modifications have been identified. A specific epitranscriptome refers to all the RNA modifications in a given biological system and is considered to play an important role in the regulations of cellular activities. Mass spectrometry-based methods have proven to be the most accurate way to identify RNA modifications and determine the amount of each detectable modification. Relating to the recent development of mapping specific RNA modifications within a transcriptome, the profiling of all RNA modifications can serve as a prescreening tool for mapping and provides support for analyzing the data obtained from mapping. In this chapter, the details for setting up a commonly used mass spectrometry-based method to profile all the RNA modifications in specific epitranscriptomes are described, and the possible options if available are discussed.
