Circrna back-splicing
WebThis splicing method is called back-splicing. 12, 17 The splicing regulatory mechanisms of circRNAs biogenesis are different from the linear isoforms. CircRNAs demonstrate significant and diverse back-splicing events catalyzed by typical spliceosome mechanisms in different cell lines. 13, 18–20 CircRNAs are pervasive in molecular biology.

Repetitive Alu sequences represent approximately 10% of the human genome. The presence of Alu elements in flanking introns of protein-coding genes adjacent to the first and last exons that form circRNAs, influence the formation of circRNAs. It is important that the flanking intronic Alu elements are complementary, as this enables RNA pairing, which in turn facilitates circRNA synthesis.
