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 factors should cross-link to the cryptic junctions; and that analogous decoy exons / splice junctions should be common in retained introns. Decoy exons promote SF3B4 i4 retention. WebMar 23, 2004 · Introns are flanked by a partially conserved coding sequence that forms the immediate exon junction sequence following intron removal from pre-mRNA. … WebIn most splicing reactions, neither cryptic site is recognized. Most mature transcripts include intron 3, while the second most frequent class lacks exon 3. Traditionally, the former class of transcripts is taken as evidence for the intron definition of splicing, while the latter class has given credence to the exon definition of splicing. simplicity 7350 belt
