摘要
Atg8 family proteins play crucial roles in autophagy to maintain cellular homeostasis. However, the physiological roles of Atg8 family proteins have not been systematically determined. In this study, we generated Atg8a and Atg8b (homologs of Atg8 in Drosophila melanogaster) knockout flies. We found that the loss of Atg8a affected autophagy and resulted in partial lethality, abnormal wings, decreased lifespan, and decreased climbing ability in flies. Furthermore, the loss of Atg8a resulted in reduced muscle integrity and the progressive degeneration of the neuron system. We also found that the phosphorylation at Ser88 of Atg8a is important for autophagy and neuronal integrity. The loss of Atg8b did not affect autophagy but induced male sterility in flies. Here, we take full advantage of the fly system to elucidate the physiological function of Atg8a and Atg8b in Drosophila.
