Circular RNAs: Novel Regulators of Neuronal Development
Circular RNAs (circRNAs) are highly stable, circularized long non-coding RNAs. circRNAs are conserved across species and appear to be specifically enriched in the nervous system. Recent studies show that many circRNAs are expressed in a tissue- and developmental-stage-specific manner, reveal a striking regulation of circRNAs during neuronal development, and detect their presence at synaptic sit...
متن کاملCircular RNAs Are the Predominant Transcript Isoform from Hundreds of Human Genes in Diverse Cell Types
Most human pre-mRNAs are spliced into linear molecules that retain the exon order defined by the genomic sequence. By deep sequencing of RNA from a variety of normal and malignant human cells, we found RNA transcripts from many human genes in which the exons were arranged in a non-canonical order. Statistical estimates and biochemical assays provided strong evidence that a substantial fraction ...
متن کاملCircular RNAs (circRNAs) in Health and Disease
Splicing events do not always produce a linear transcript. Circular RNAs (circRNAs) are a class of RNA that are emerging as key new members of the gene regulatory milieu, which are produced by back-splicing events within genes. In circRNA formation, rather than being spliced in a linear fashion, exons can be circularised by use of the 3' acceptor splice site of an upstream exon, leading to the ...
متن کاملCircular RNAs are depleted of polymorphisms at microRNA binding sites
MOTIVATION Circular RNAs (circRNAs) are an abundant class of highly stable RNAs that can affect gene regulation by binding and preventing microRNAs (miRNAs) from regulating their messenger RNA (mRNA) targets. Mammals have thousands of circRNAs with predicted miRNA binding sites, but only two circRNAs have been verified as being actual miRNA sponges. As it is unclear whether these thousands of p...
متن کاملBiogenesis of Circular RNAs
Circular RNAs are generated during splicing through various mechanisms. Ashwal-Fluss et al. demonstrate that exon circularization and linear splicing compete with each other in a tissue-specific fashion, and Zhang et al. show that exon circularization depends on flanking intronic complementary sequences. Both papers show that several types of circular RNA transcripts can be produced from a sing...
