WebThere was lesser constraint on lower-scoring bins of cryptic splice donors, but clear selection remained at the same position relative to RPs (Supplementary Figure 9). Thus, there is a strong evolutionary constraint on cryptic splice donors, even though their exons are ultimately not utilized in mature mRNAs. Overall, the strong sequence and ... Webeliminates splicing from the wild-type donor site, but activates a cryptic splice site in the middle of exon 1 in vitro (Felber et al, 1982).
