Comprehensive identification of internal structure and alternative splicing events in circular RNAs
Open accessAbstract
Although previous studies demonstrated circular RNAs (circRNAs) does not exclusively comprise mRNA exons, no study has extensively explored their internal structure. By combining an algorithm with long-read sequencing data and experimental validation, we, for the first time, comprehensively investigate internal components of circRNAs in 10 human cell lines and 62 fruit fly samples, and reveal the prevalence of alternative splicing (AS) events within circRNAs. Significantly, a large proportion of circRNA AS exons can hardly be detected in mRNAs and are enriched with binding sites of distinct splicing factors from those enriched in mRNA exons. We find that AS events in circRNAs have a preference towards nucleus localization and exhibit tissue- and developmental stage-specific expression patterns. This study suggests an independent regulation on the biogenesis or decay of AS events in circRNAs and the identified circular AS isoforms provide targets for future studies on circRNA formation and function.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
