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 …
WebCircRNAs are generated mainly from exonic or intronic sequences, and in their biogenesis, reverse complementary sequences and RNA binding proteins (RBP) play an important role.
