Intronic splicing silencer

WebDec 17, 2004 · Exonic splicing silencers (ESSs) are cis-regulatory elements that inhibit the use of adjacent splice sites, often contributing to alternative splicing (AS). To systematically identify ESSs, an in vivo splicing reporter system was developed to screen a library of random decanucleotides. The screen yielded 141 ESS decamers, 133 of which … Webintronic splicing silencer (ISS) motifs have positive scores, while exonic splicing silencer (ESS) and intronic splicing enhancer (ISE) motifs have negative scores. Red vertical lines below the x-axis represent AG 3’ splice site (ss).

WebIn addition, the possible poison exon group had a smaller density of 3′ ss intronic splicing silencers compared to dystrophin CEs. To our knowledge, our findings indicate for the first time that poison exons might exist in DMD (the dystrophin gene) and present with different splicing characteristics than other dystrophin PEs and CEs.

Exonic splicing silencers work by inhibiting the splicing of pre-mRNA strands or promoting exon skipping. The single stranded pre-mRNA molecules need to have their intronic and exonic regions spliced in order to be translated. ESSs silence splice sites adjacent to them by interfering with the components of the core splicing complex, such as the snRNP's, U1 and U2. This causes proteins that negatively influence splicing to be recruited to the splicing machinery. WebNational Center for Biotechnology Information
