Autophagy involves the sequestration of portions of cytoplasm by double-membraned autophagosomes, which are then trafficked to lysosomes. After autophagosome-lysosome fusion, the contents of the autophagosomes are degraded by lysosomal hydrolases. SNAREs [soluble N-ethylmaleimide-sensitive fusion (NSF) attachment protein receptors] are molecules that mediate vesicular fusion events. Here, we review recent data implicating SNAREs as having key roles both in the genesis of autophagosomes, as well as in autophagosome lysosome fusion, and we discuss the implications of these findings in the context of a long-standing mystery: the origin of autophagosomes.
