1 A ubiquitin-like system mediates the conjugation of the C terminus of Atg8 to the lipid phosphatidylethanolamine (PE), and this conjugate (Atg8-PE) plays a crucial role in autophagosome formation at the phagophore assembly site/pre-autophagosomal structure (PAS). Aminosalicylic Acid ubiquitin-like protein ATG8 Saccharomyces cerevisiae S288C
2 A ubiquitin-like system mediates the conjugation of the C terminus of Atg8 to the lipid phosphatidylethanolamine (PE), and this conjugate (Atg8-PE) plays a crucial role in autophagosome formation at the phagophore assembly site/pre-autophagosomal structure (PAS).

3 We find that Atg8-PE accumulates on various organelle membranes including the vacuole, the endosome and the ER in these cells, which depletes unlipidated Atg8 and thereby attenuates its localization to the PAS. Aminosalicylic Acid ubiquitin-like protein ATG8 Saccharomyces cerevisiae S288C
