| Outline of Final Research Achievements |
Ezrin is the most abundantly expressed ERM (ezrin, radixin, moesin) protein in the glomerular podocytes, and is also reported to form multi-protein complex with several membrane proteins and other scaffold proteins whereas the physiological roles still remain unclear. In this study, we investigated the physiological importance of ezrin in the regulation of glomerular podocyte function by using ezrin knockdown mice. Ezrin deficient mice did not exhibit apparent glomerular dysfunction. However, loss of ezrin protected podocytes from drug-induced morphological changes in ezrin knockdown mice. Our results suggest that ezrin is involved in the regulation of cell motility in the glomerular podocytes.
