Circular RNAs (circRNAs) are produced from precursor RNA back-splicing. Recent findings reveal the complexity of the biogenesis of circRNAs and their cell type-specific expression. They also show that circRNAs can shape eukaryotic transcriptomes by sequestering microRNAs and by regulating transcription and interfering with splicing.
