A dynamic membrane rearrangement occurs in cells during autophagy to form autophagosomes. In this dynamic process, two ubiquitin-like modifications, Apg12p-conjugation and LC3-modification, are essential for the formation of autophagosomes. Apg7p and Apg10p catalyze the conjugation of Apg12p to Apg5p. The same Apg7p and Apg3p catalyze the processing of LC3 to a membrane-bound form, LC3-II. In this paper, we investigated whether Apg12p has an influence on the second LC3-modification system. A cross-linking experiment revealed that Apg3p interacts with the endogenous Apg12p.Apg5p conjugate. However, Apg3p itself interacts with free Apg12p more preferentially than the Apg12p.Apg5p conjugate, when free Apg12p exists. When Apg12p was overexpressed, LC3 processing was significantly enhanced in the presence of Apg7p. In contrast, when the Apg12p.Apg5p conjugate itself was accumulated by the overexpression of Apg12p and Apg5p, LC3 processing was dominantly inhibited, even in the presence of Apg7p. These results indicate that both Apg12p and the Apg12p.Apg5p conjugate are regulatory factors for LC3 processing.
