WebEach RBD/RRM has its own sequence preference and typically binds to a region of 2–6 nt in single-stranded RNA [15,18]. In this study, we found that the RBP Rbm38 suppresses the transcription elongation defect caused by splicing deficiency, and that the N- and C-terminal regions and the RBD/RRM domain of Rbm38 are required for this suppression. WebIn metazoans, alternative splicing of genes is essential for regulating gene expression and contributing to functional complexity. Computational predictions, comparative genomics, and transcriptome profiling of normal and diseased tissues indicate that an unexpectedly high fraction of diseases are caused by mutations that alter splicing. Mutations in cis …
Pre-mRNA splicing in disease and therapeutics - ScienceDirect
Webbinding Fox (Rbfox) family has recently been characterized as phylogenetically conserved regulators of alternative splicing (Jin et al., 2003; Nakahata and Kawamoto, 2005; ... tain the RRM, are identical except that Rbfox3-L including a 47 aa-insertion in the C-terminal region. Consistent with pre- WebIt is reported here that sequence-specific binding of the conserved Rbfox RRM to miRNA precursors containing the same sequence motif in their terminal loops, including miR-20b and miR -107, suppresses their nuclear processing. Rbfox proteins regulate tissue-specific splicing by targeting a conserved GCAUG sequence within pre-mRNAs. We report here … check sheet purpose
Developmental regulation of RNA processing by Rbfox proteins
WebMay 19, 2016 · Rbfox proteins regulate tissue-specific splicing by targeting a conserved GCAUG sequence within pre-mRNAs. We report here that sequence-specific binding of the … WebDec 23, 2024 · The RbFox RRM binds RNAs with a consensus 5'-GCAUG motif with low nanomolar affinity . in vitro. 16-19. Even minor changes in the consensus motif decrease … WebWe explored the mechanisms of RBFOX splicing activation and repression using an MS2-tethering assay. We found that the Ala/Tyr/Gly-rich C-terminal domain is sufficient for exon activation when tethered to the downstream intron, whereas both the C-terminal domain and the central RRM are required for exon repression when tethered to the upstream intron. flat rental mitcham
