摘要


Many pre-mRNAs are alternatively spliced in a tissue-specific manner in multicellular organisms. The Fox-1 family of RNA-binding proteins regulate alternative splicing by either activating or repressing exon inclusion through specific binding to UGCAUG stretches. However, the precise cellular contexts that determine the action of the Fox-1 family in vivo remain to be elucidated. We have recently demonstrated that ASD-1 and FOX-1, members of the Fox-1 family in Caenorhabditis elegans, regulate tissue-specific alternative splicing of the fibroblast growth factor receptor gene, egl-15, which eventually determines the ligand specificity of the receptor in vivo. Here we report that another RNA-binding protein, SUP-12, coregulates the egl-15 alternative splicing. By screening for mutants defective in the muscle-specific expression of our alternative splicing reporter, we identified the muscle-specific RNA-binding protein SUP-12. We identified juxtaposed conserved stretches as the cis elements responsible for the regulation. The Fox-1 family and the SUP-12 proteins form a stable complex with egl-15 RNA, depending on the cis elements. Furthermore, the asd-1; sup-12 double mutant is defective in sex myoblast migration, phenocopying the isoform-specific egl-15(5A) mutant. These results establish an in vivo model that coordination of the two families of RNA-binding proteins regulates tissue-specific alternative splicing of a specific target gene.
