Outline of Final Research Achievements |
We have reported that the complex of small G protein Ras and its target molecule PI3K is localized in the endosomes and controls endocytosis and viral particle internalization. However, the molecular mechanism by which the Ras-PI3K complex is localized is the endosome remains unknown. In this study, the amino acid sequence responsible for the above phenomenon was identified. By screening the binding protein for the sequence, a mitochondrial protein was identified. Knockdown of this mitochondrial protein inhibited the translocation of Ras-PI3K complex to the endosome, endocytosis, and mitochondrial-endosome interaction, suggesting that binding of PI3K and the factor regulates endocytosis through interaction between organelles.
