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. WebExonic circRNAs (ecircRNAs) EcircRNA consists of one or multiple exons, which is the most common type (more than three-fourths of the whole). 8 There are two types of ecircRNA formation, namely, direct back-splicing, and exon skipping. 9 The direct back-splicing model includes two mechanisms, intron-pairing-driven, and RNA-binding …
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 … WebCircular RNA (or circRNA) is a type of single-stranded RNA which, unlike linear RNA, forms a covalently closed continuous loop. In circular RNA, the 3' and 5' ends normally present in an RNA molecule have been joined together. This feature confers numerous properties to circular RNA, many of which have only recently been identified. Many types of circular …

WebCircular RNAs (circRNAs) are a recently discovered class of RNAs derived from protein-coding genes that have important biological and pathological roles. They are formed through backsplicing during co-transcriptional alternative splicing; however, the unified mechanism that accounts for backsplicing decisions remains unclear. Factors that regulate the …
WebFeb 10, 2024 · The biogenesis of circRNAs is now known to be regulated by multiple specific factors; however, circRNAs were previously thought to be insignificant byproducts of splicing errors.
