| Outline of Final Research Achievements |
The nucleolus, in which rRNA is transcribed and processed, and ribosomal subunits are formed in eukaryotic cells, disassembles and reassembles every cell division. The number and size of the nucleolus are typical of cell types, but the mechanism to control them is largely unknown. We found that Nepro, which is necessary for the maintenance of early neural stem cells in the neocortex, is also crucial for the size and number of the nucleolus in preimplantation embryos. We have also found that Nepro is localized in a specific part of the nucleolus, and its QVEQC, hydrophobic and DDIDDIF domains, and nuclear localization signal are necessary for the function of Nepro.
