RNA editing deaminases act on a variety of targets in different organisms. A number of such enzymes have been shown to act on mRNA, with the resultant nucleotide changes modifying a transcript’s information content. Though the deaminase activity of mRNA editing enzymes is readily demonstrated in vitro, identifying their physiological targets has proved challenging. Recent advances in ultra highthroughput sequencing technologies have allowed for whole transcriptome sequencing and expression profiling (RNA-Seq). We have developed a system to identify novel mRNA editing deamination targets based on comparative analysis of RNA-Seq data. The efficacy and utility of this approach is demonstrated for APOBEC1, a cytidine deaminase with a known and well-characterized mRNA editing target in the mammalian small intestine.
