| Outline of Final Research Achievements |
Yeast is a microbe that contributes to bread making and alcohol fermentation. Incorporation of lactic acid and pyruvate by yeast is inhibited in a medium containing glucose. This phenomenon is partly due to glucose-induced endocytic degradation, so-called as glucose inactivation, of Jen1. It is known that glucose inactivation of Jen1 is triggered by its ubiquitination by Rsp5-Rod1 ubiquitin ligase complex. We discovered that the C-terminal 20-amino-acid region of Jen1 recognized by Rsp5-Rod1 complex and sufficient to induce glucose inactivation of transmembrane transporter.
