Macroautophagy becomes a major route for the clearance of protein aggregates that are normally poor substrates for the proteasome, the other protein quality-control machinery. As a flux process, macroautophagy (hereafter referred to as autophagy) involves the formation of the autophagosome, a double-membrane vesicle for engulfing unwanted cellular components such as protein aggregates, and the fusion of autophagosomes with lysosomes that contain many potent proteases for final degradation.展开更多
