Abstract Eukaryotic cells express a myriad of circular RNAs (circRNAs), many of them displaying tissue‐specific expression patterns. They arise from linear precursor RNAs in which 5′ and 3′ ends become covalently ligated. Given these features, biochemical and computational approaches traditionally used to study linear RNA must be adapted for analysis of circular RNAs. Such circRNA‐specific methodologies are allowing the systematic identification of circRNAs and the analysis of their biological functions. Here, we review the resources and molecular methods currently utilized to quantify circRNAs, visualize their distribution, identify interacting partners, and elucidate their function. We discuss the challenges of analyzing circRNAs and propose alternative approaches for studying this unique class of transcripts.
