| Research Abstract |
In the eukaryotic cells, many kinds of vesicular organelles which are composed of the lipid bilayer exchange their contents by a vesicle transport. In a vesicle transport, the budding and fusion of the membranes are tightly regulated. When a cell divides during mitosis, vesicular organelles should be separated equally into two daughter cells. To this end, cells actively inhibit the membrane fusion to make the vesicular organelles small and increase their number. In this work, we have shown that Plk1, a Ser/Thr kinase that is known to function during mitosis, is necessary for the inhibition of the membrane fusion during mitosis, and identified a candidate molecule for the target of Plk1.
