WebJul 10, 2024 · Finally, we wondered whether disruption of 5′ splice-donor and 3′ splice-acceptor site in the cassette exon would affect SRSF2-mediated 3′AG′ activation. We tested another mutant minigene, E7-ss-mut, where the splice-site sequences of exon 7 were abolished, effectively converting E6-8 to a two exon minigene (Figure 4C, left panel). 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).
