WebBiogenesis of circRNAs. In all eukaryotes, the removal of introns and linking exons is a major part of the RNA splicing process, transforming the precursor mRNAs (pre-mRNAs) containing introns into intron-less mRNAs. Most eukaryotic circRNAs are produced by pre-mRNAs. In recent years, another common splicing method has been found in eukaryotes. WebMar 3, 2024 · The biogenesis of circRNAs is widely regulated by general cis-regulatory elements (non-coding binding regions capable of regulating transcription) and trans-acting factors.21 For instance, a reverse complementary sequence or inverted tandem repeating in flanking introns, such as Alu elements, is reported to facilitate intron pairing and the ...
