| Research Abstract |
Permeability of the nuclear envelope (NE) was investigated using a photoconvertible fluorescent protein, KikGR. It is widely believed that the barrier of the NE against the macromolecule diffusion is established at the end of mitosis and it does not change along the cell cycle. But, in this study, it was revealed that the barrier is loose at least during the first 30 minutes after cytokinesis. Furthermore, during the first 10 minutes, molecules with a molecular mass of as large as 210k can pass through the NE.
