| Research Abstract |
Autophagy is a conserved eukaryotic process of vacuolar/lysosomal-mediated degradation targeting proteins and organelles. Autophagy is characterized by the formation of a cytosolic double-membrane structure, the autophagosome. The molecular mechanisms underlying the process of autophagy remain to be elucidated. Here, I demonstrate that Atg1 kinase, the substrates of which were unknown, phosphorylates Atg13 and Vps34. In addition, I identify a novel component of the PI3 kinase complex, Atg38. Atg38 is required for the integrity of this complex.
