A review consolidating research across multiple species including human, mouse, and rat indicates that the circPAIP2, a nuclear exon-intron circRNA, enhances transcription of its parental PAIP2 gene in a positive feedback loop by interacting with U1 snRNP complexes and RNA polymerase II [Chan et al.
