Switch-like regulation of tissue-specific alternative pre-mRNA processing patterns revealed by customized fluorescence reporters
Alternative processing of precursor mRNAs (pre-mRNAs), including alternative transcription start sites, alternative splicing and alternative polyadenylation, is the major source of protein diversity and plays crucial roles in development, differentiation and diseases in higher eukaryotes. It is esti...

description | Alternative processing of precursor mRNAs (pre-mRNAs), including alternative transcription start sites, alternative splicing and alternative polyadenylation, is the major source of protein diversity and plays crucial roles in development, differentiation and diseases in higher eukaryotes. It is estimated from microarray analyses and deep sequencing of mRNAs from synchronized worms that up to 25% of protein-coding genes in Caenorhabditis elegans undergo alternative pre-mRNA processing and that many of them are subject to developmental regulation. Recent progress in visualizing the alternative pre-mRNA processing patterns in living worms with custom-designed fluorescence reporters has enabled genetic analyses of the regulatory mechanisms for alternative processing events of interest in vivo. Expression of the tissue-specific isoforms of actin depolymerising factor (ADF)/cofilin, UNC-60A and UNC-60B, is regulated by a combination of alternative splicing and alternative polyadenylation of pre-mRNA from a single gene unc-60. We recently found that muscle-specific splicing regulators ASD-2 and SUP-12 cooperatively switch the pre-mRNA processing patterns of the unc-60 gene in body wall muscles. Here I summarize the bichromatic fluorescence reporter system utilized for visualizing the tissue-specific alternative processing patterns of the unc-60 pre-mRNA. I also discuss the model for the coordinated regulation of the UNC-60B-type pre-mRNA processing in body wall muscles by ASD-2 and SUP-12. |
