Outline of Final Research Achievements |
Selective autophagy is thought to maintain intracellular homeostasis by eliminating unwanted/dangerous materials. Although it has been shown that Atg proteins accumulate on the substrate in selective autophagy, events that happen afterwards are not clear. In this study, we discovered that the forced recruitment of LC3 to mitochondria is sufficient to induce mitochondrial degradation. We hypothesize that mitochondrial fission is induced at the contact site with the isolation membrane, which later engulfs the mitochondrial fragment generated by the fission. Moreover, this study suggests the existence of unidentified mitochondrial fission factors responsible for the mitochondrial fission during selective autophagy of mitochondria.
