RNA editing is a widespread molecular phenomenon occurring in a variety of organisms. In humans, it mainly involves the deamination of adenosine to inosine (A-to-I) in double-stranded RNAs by ADAR enzymes. A-to-I RNA editing has been investigated in different tissues as well as in diverse experimental and pathological conditions. By contrast, its biological role in single cells has not been explored in depth. Recent methodologies for cell sorting in combination with deep sequencing technologies have enabled the study of eukaryotic transcriptomes at single cell resolution, paving the way to the profiling of their epitranscriptomic dynamics. Here we describe a step-by-step protocol to detect and characterize A-to-I events occurring in publicly available single-cell RNAseq experiments from human alpha and beta pancreatic cells.
