Circrna back-splicing
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. WebMay 21, 2024 · A Back-splicing driven by the pairing of intronic complementary sequences, RNA-binding protein (RBP), or lariat structure containing skipped exons or introns. B …
