Connections Between SNAREs and Autophagy


Connections Between SNAREs and Autophagy

Kevin Moreau et al. Trends Biochem Sci.


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.
