Research Interests:

- Cytoskeleton-Cell Biology We are interested in the mechanisms of the regulation of actin cytoskeletal dynamics. Actin filaments are reorganized during development, cell migration, and cell division. Proper regulation of the actin reorganization is required for normal celluler activities, while its misregulation often causes diseases. We have been studying functions of actin-binding proteins using biochemical, cell biological, and genetic techniques.
- Alternative pre-mRNA splicing A number of genes produce mutiple transcripts by alternative splicing. Misregulation of this mechanism is involved in the pathogenesis of myotonic dystrophy. We identified a muscle-specific regulator of pre-mRNA splicing in the nematode C. elegans and have been studying how this splicing factor functions. This splicing factor is conserved in humans, and we hope to gain insights into the mechanism of tissue-specific pre-mRNA splicing.
