Abstract
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 demonstratedin vitro, identifying their physiological targets has proved challenging. Recent advances in ultra high-throughput 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.
