Modulation of alternative splicing by long-range RNA structures in Drosophila
Accurate and efficient recognition of splice sites during pre-mRNA splicing is essential for proper transcriptome expression. Splice site usage can be modulated by secondary structures, but it is unclear if this type of modulation is commonly used or occurs to a significant degree with secondary structures forming over long distances. Using phlyogenetic comparisons of intronic sequences among 1...
متن کاملIdentification of alternative splicing regulators by RNA interference in Drosophila.
Alternative splicing is thought to be regulated by nonspliceosomal RNA binding proteins that modulate the association of core components of the spliceosome with the pre-mRNA. Although the majority of metazoan genes encode pre-mRNAs that are alternatively spliced, remarkably few splicing regulators are currently known. Here, we used RNA interference to examine the role of >70% of the Drosophila ...
متن کاملConserved RNA secondary structures promote alternative splicing.
Pre-mRNA splicing is carried out by the spliceosome, which identifies exons and removes intervening introns. Alternative splicing in higher eukaryotes results in the generation of multiple protein isoforms from gene transcripts. The extensive alternative splicing observed implies a flexibility of the spliceosome to identify exons within a given pre-mRNA. To reach this flexibility, splice-site s...
متن کاملRole of Aberrant Alternative Splicing in Cancer
Alternative splicing can alter genome sequence and as a consequence, many genes change to oncogenes. This event can also affect protein function and diversity. The growing number of study elucidate the pathological influence of impaired alternative splicing events on numerous disease including cancer. Here, we would like to highlight the significant role of alternative splicing in cancer biolog...
متن کاملEvidence for Widespread Association of Mammalian Splicing and Conserved Long-Range RNA Structures
Pre-mRNA structure impacts many cellular processes, including splicing in genes associated with disease. The contemporary paradigm of RNA structure prediction is biased toward secondary structures that occur within short ranges of pre-mRNA, although long-range base-pairings are known to be at least as important. Recently, we developed an efficient method for detecting conserved RNA structures o...
