| Outline of Final Research Achievements |
This study aimed to clarify the function of the intrinsically disordered protein, NPM1. NPM1 is mainly localized to the nucleoli and regulates the ribosome biogenesis, although its detailed function and the mechanism undelaying this function was unclear. In addition, NPM1 has been suggested to play a crucial role in the gene expression program in growing cells. However, it has been currently not known how NPM1 is involved in the regulation of the gene expression. In this study, we clarified the molecular mechanism by which NPM1 maintains the nucleolar structure. Furthermore, we demonstrated that NPM1 regulates the expression of the genes critical for immune response, inflammatory response, and oncogenesis.
