Outline of Final Research Achievements

Research on autophagy has been widespread, but it still has the drawback of weak biochemical verification. The purpose of this study was to clarify what, when and how cytoplasmic component are degraded by autophagy. Taking advantage of the yeast system, which has accumulated a lot of knowledge, we have established a new method and gave a new perspective on the accurate grasp of degradation targets and final degradation products and their effects on cell metabolism.

Academic Significance and Societal Importance of the Research Achievements

オートファジー研究は、今日哺乳動物における生理的役割に関して目覚ましい展開を見ているが、その分子レベルの理解に関しては、多くのことがブラックボックスとして残されている。本研究は30年以上の酵母の系での実績と、系の優位性を生かし、分解基質、分解過程、分解産物の解析を通じて、今一度高等動植物のオートファジー研究に新しい視点を与えることを目指してきたが、一定の成果をあげることができたと考えている。
