| Outline of Final Research Achievements |
Ezrin is an actin-binding protein which cross-links between plasma membrane proteins and cytoskeletons. It is essential for morphogenesis of the apical domain of epithelial cells as well as neuronal tissues. Recently, ezrin has been reported to be involved in targeting of specific transport proteins to the cell surface under the control of hormones and cellular signals. In this research project, we studied the pathophysiological roles of ezrin using the “ezrin-knock-down mice”, and focused on its roles on epithelial architecture and transport as well as neuritogenesis. Here, we newly found that ezrin is involved in cell surface expression of a phosphate transporter, Npt2a in the renal proximal tubules, and of a chloride channel, CFTR in the cholangiocytes. Therefore, ezrin is an essential protein for phosphate re-absorption in kidneys, and regulation of bile flow in bile ducts. Ezrin is also involved in neuritogenesis of cortical neurons.
