Biogenesis and functions of circular RNAs. (A) A gene can be transcribed and spliced into linear and circular RNAs. Note the unique ‘head-to-tail’ splice junctions formed by an acceptor splice site at the 5′ end of an exon and a donor site at the 3′ end of a downstream exon. A demonstrated role for circRNAs is to act as a microRNA sponge. (B) Pictograms of additional plausible options for circRNA function. See main text for details.
