Research Abstract

We have demonstrated that for the establishment of cell polarity, stabilization and bundling of microtubule are essential and that molecules implicated in epithelial morphogenesis such as MID1 encoded by a causative gene of Opitz syndrome and its related protein MID2 play important role in the stabilization/bundling of microtubules. Thus we have been able to propose that this remodeling of microtubules allows the trafficking of secreted vesicles and cell polarity factors on the rail of bundled microtubules.
