Reserach Interests

Alternative splicing of pre-mRNAs greatly expands the coding potential and the complexity of the genome by producing multiple protein isoforms. Regulation of alternative splicing is achieved by the interaction of trans-acting splicing factors with cis-acting sequences found within introns and/or exons. The RNA-binding protein Rbfox1 belongs to the Rbfox family of splicing regulatory proteins which also includes Rbfox2 and Rbfox3. Members of this family regulate the inclusion or exclusion of alternative exons by binding to the sequence (U)GCAUG downstream or upstream of the regulated exon, respectively. Rbfox1 is specifically expressed in the brain, heart and skeletal muscle. Recently, conditional knock out mice for this RNA binding protein in the central nervous system showed a critical role played in neuronal function. The high expression of Rbfox1 in skeletal muscle has challanged us to investigate its role in muscle physiology. I am currently working on the generation of two conditional knock out mouse models for Rbfox1 in the skeletal muscle to determine the roles of Rbfox1 in skeletal muscle development and maintenance.
