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. We analyzed these mutations with four different splice ... WebMar 15, 2001 · Two other cryptic splice sites, 3135-3136 GT and 3165-3166 GT situated in exon 4 (numbering according to Genbank accession number M64982) are also used. …
The Exon Junction Complex and intron removal prevent re-splicing …
WebSep 1, 2024 · Cryptic splice site. Splicing occurs at the 5′ and 3′ ends of intronic regions of the precursor messenger RNAs (pre-mRNA), which are known as 5′ and 3′ splice sites. The splicing is promoted by a spliceosome complex which recognizes the exon-intron boundaries and removes the intron with single nucleotide precision. When genes are … WebJul 10, 2024 · However, in the absence of a strong cryptic splice-site, alternative cryptic 3′ss splicing using a less conserved, weaker 3′AG′ might be possible when SRSF2 is present. These results raised the possibility that yet another cryptic splice-site, in the absence of both 3′AG′1 and 3′AG′2, could mediate alternative splicing of the SMN ... grab receipts summary

Conservation of the weak … WebOct 30, 2024 · We detected three types of AS events (Fig. 1c): IR; alternative splice site variants (ASSV); and splicing of cryptic introns (i.e. introns with both splice sites located within an annotated coding exon). It is important to note that the classification of splice variants relies on the definition of a canonical form ...
