Outline of Final Research Achievements

Ribosome are macromolecular machines that perform protein synthesis. Ribosomopathies are a collection of disorders of ribosome dysfunction characterized by a defect in ribosome biogenesis. In this study, we found that Nol9 is involved in ribosom synthesis, dysfunction of Nol9 causes ribosomopathy-like phenotype.

Academic Significance and Societal Importance of the Research Achievements

これまで、リボソーム病を引き起こす分子の異常はいくつか知られていたが、ポリヌクレオチドキナーゼの異常がリボソーム病に寄与することはあまり分かっていなかった。本研究により、ポリヌクレオチドキナーゼの生理的役割の一部を明らかにした。またリボソーム病の病態形成機構の一端が明らかとなり、新たな治療法の開発につながる成果が得られた。
