Biogenesis of circrnas
WebJan 17, 2024 · In 2013, a novel type of circRNAs consisting of only introns, referred to as ciRNA, was discovered in human cells. It is mainly presented in the nucleus and is involved in the transcriptional regulation of its parental genes [14, 15]. ciRNA biogenesis requires a consensus motif consisting of both a 7 nt GU-rich element near the 5′ splice site and an … WebCircular RNA (or circRNA) is a type of single-stranded RNA which, unlike linear RNA, forms a covalently closed continuous loop.
