Muscleblind-like 1 (Mbnl1) regulates pre-mRNA alternative splicing during terminal erythropoiesis.
The scope and roles of regulated isoform gene expression during erythroid terminal development are poorly understood. We identified hundreds of differentiation-associated isoform changes during terminal erythropoiesis. Sequences surrounding cassette exons of skipped exon events are enriched for motifs bound by the Muscleblind-like (MBNL) family of splicing factors. Knockdown of Mbnl1 in culture...
متن کاملTranscriptome-wide Regulation of Pre-mRNA Splicing and mRNA Localization by Muscleblind Proteins
The muscleblind-like (Mbnl) family of RNA-binding proteins plays important roles in muscle and eye development and in myotonic dystrophy (DM), in which expanded CUG or CCUG repeats functionally deplete Mbnl proteins. We identified transcriptome-wide functional and biophysical targets of Mbnl proteins in brain, heart, muscle, and myoblasts by using RNA-seq and CLIP-seq approaches. This analysis ...
متن کاملMuscleblind protein, MBNL1/EXP, binds specifically to CHHG repeats.
Myotonic dystrophy (DM) type 1 is caused by an expansion of a CTG repeat in the DMPK gene and type 2 by a CCTG repeat in the ZNF9 gene. Previous reports have suggested that transcripts containing expanded CUG/CCUG repeats might have toxic gain-of-function effects, probably affecting the function of RNA-binding proteins in the pathogenesis of DM. Here, it was attempted to compare the RNA-binding...
متن کاملRNAcatalyses nuclear pre-mRNA splicing
In nuclear pre-messenger RNA splicing, introns are excised by the spliceosome, a dynamic machine composed of both proteins and small nuclear RNAs (snRNAs). Over thirty years ago, after the discovery of self-splicing group II intron RNAs, the snRNAswere proposed to catalyse splicing. However, no definitive evidence for a role of either RNAor protein in catalysis by the spliceosome has been repor...
متن کاملMuscleblind-like 1 (Mbnl1) promotes insulin receptor exon 11 inclusion via binding to a downstream evolutionarily conserved intronic enhancer.
The insulin receptor exists as two isoforms, IR-A and IR-B, which result from alternative splicing of exon 11 in the primary transcript. These two isoforms show a cell-specific distribution, and their relative proportions also vary during development, aging, and in different disease states. We have previously demonstrated that both intron 10 and the alternatively spliced exon 11 contain regulat...
