Adenosine-to-inosine (A-to-I) RNA editing is a post-transcriptional processing event involved in diversifying the transcriptome responsible for various biological processes. Although bioinformatic approaches have predicted a number of A-to-I editing sites in cDNAs, the human transcriptome is thought to still harbor large numbers of as-yet-unknown editing sites. Exploring new editing sites requires a biochemical method to accurately identify inosines on RNA strands. We have developed a chemical method to identify inosines, called ICE (inosine chemical erasing), that is based on cyanoethylation combined with reverse transcription. We employed this method to carriy out large-scale identification of novel editing sites in the human brain transcriptome.
