Outline of Final Research Achievements

TOR (target of rapamycin) complex I is a highly conserved protein kinase complex that functions as a nutrient/stress-sensitive, central controller of cell growth and aging. In this study, using yeast mutant strains and approach to localize proteins artificially, we found that sphingolipids regulate TORC1 though the upstream regulator EGO complex. In addition, our data suggested that sphingolipid-mediated TORC1 regulation is tightly linked to the TORC2 signaling pathway and the structure and function of vacuoles.

Academic Significance and Societal Importance of the Research Achievements

老化,寿命,癌,肥満などの疾患に関与する主要シグナル分子TOR(Target of Rapamycin) の活性は,栄養源やストレスなど多様なシグナルにより制御されるが,その制御機構は不明な点が多い。本研究で,生体膜の主要成分であるスフィンゴ脂質がTORC1の上流で機能するタンパク質複合体の制御を介してTORC1を調節していることが明らかになった。また,スフィンゴ脂質によるTORC1の調節には,構成因子と機能が異なる別のTOR複合体2(TORC2)を介したシグナル経路も深く関わっていることも明らかとなり,TORC1の制御機構およびTOR複合体間の機能連携の理解の進展に貢献した。
