WebJul 10, 2024 · Here we show that the serine/arginine rich splicing factor 2 (SRSF2) promotes cryptic 3′ splice-site (3′AG′) usage during cassette exon exclusion in survival of motor neuron (SMN2) minigenes. Deletion of the 3′AG′ (3′AG′1), its associated branch point (BP′) and polypyrimidine tract (PPT′) sequences directs SRSF2 to promote a … WebJul 19, 2006 · In fact, cryptic splice site activation in the β-globin gene was one of the first medically relevant splicing defects described ( 78, 79 ). The usage of alternative splice sites following the inactivation of the proper site often leads to a frameshift in the protein coding sequence.

Eukaryotic genomes contain large numbers of splice sites, known as cryptic splice sites (css), which are generally held to be disadvantageous sites that are dormant or used only at low levels unless activated by mutation of nearby authentic or advantageous splice sites (1,2). Once activated, css may be used … See more The CSF program is designed to identify transcripts that are generated through the low level use of css by normal genes. In addition, CSF also identifies a subset of alternative splice sites that are similar to css, but are used at … See more Reserch grants from Biotechnology and Biosciences Research Council and Atazoa.

WebSome splice-site mutations have an intermediate effect upon splicing that permits the production of a low level of properly spliced mRNA. An excellent example is the 3849 + 10kbC → T mutation. This mutation activates a cryptic splice donor site in intron 19 causing the inclusion of a novel 84 basepair exon into CFTR mRNA transcripts (45). WebThis mutation weakens a branch site and activates a cryptic acceptor splice site, causing the insertion of 14 intronic nucleotides into the mRNA. Conclusion: We found three different mutations, one exonic, one in a donor splice site and one intronic, that all caused missplicing of pre-mRNA.
