"WebMay 25, 2024 · We hypothesized that the EJC, recruited to the exon 13/14 junction, suppresses the cryptic 5’ SS on exon 14 and activates the canonical 5’ SS during removal of intron 14. We tested this using a minigene reporter consisting of exon 14 (containing the cryptic 5’ SS) and its immediately flanking introns and exons (Fig 3D, genomic). " - Cryptic intron vs exon

TDP-43 represses cryptic exon inclusion in the FTD–ALS gene

Several methods of RNA splicing occur in nature; the type of splicing depends on the structure of the spliced intron and the catalysts required for splicing to occur. The word intron is derived from the terms intragenic region, and intracistron, that is, a segment of DNA that is located between two exons of a gene. The term i… WebApr 21, 2024 · This model suggested several testable predictions: that deleting decoy exons or mutating their splice sites should reduce intron retention; that known 3’ splice site …
