Outline of Final Research Achievements

We have constructed fluorescence splicing reporter minigenes to visualize heart-specific alternative splicing of the TTN gene. We utilized the reporter system to analyze the heart-specific splicing regulation by RBM20. Mutations in the RBM20 gene identified in the dilated cardiomyopathy patients are enriched in the RSRSP stretch and we found that the RSRSP stretch is phosphorylated in cells and is crucial for RBM20 to be localized in the nucleus. The fluorescence TTN splicing reporter cell lines, RBM20-expressing cell lines and the anti-phospho-RBM20 antibody generated in this study can further be utilized in analyzing the effects of mutations in the RBM20 and screening for chemicals that can modify the function and localization of RBM20.
