A mitochondrial-derived vesicle HOPS to endolysosomes using Syntaxin-17
Damaged mitochondrial content is packaged in mitochondrial-derived vesicles (MDVs), which are targeted for degradation through an unclear mechanism. McLelland et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201603105) show that the SNARE Syntaxin-17 mediates MDV fusion with endolysosomes, promoting the delivery of mitochondrial cargo to lysosomes for degradation.
متن کاملLegionella blocks autophagy by cleaving STX17 (syntaxin 17)
Pathogens subvert host defense systems including autophagy and apoptosis for their survival and proliferation. Legionella pneumophila is a Gram-negative bacterium that grows in alveolar macrophages and causes severe pneumonia. Early during infection Legionella secretes effector proteins that convert the plasma membrane-derived vacuole containing Legionella into an endoplasmic reticulum (ER)-lik...
متن کاملThe HOPS complex mediates autophagosome–lysosome fusion through interaction with syntaxin 17
Membrane fusion is generally controlled by Rabs, soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs), and tethering complexes. Syntaxin 17 (STX17) was recently identified as the autophagosomal SNARE required for autophagosome-lysosome fusion in mammals and Drosophila. In this study, to better understand the mechanism of autophagosome-lysosome fusion, we searched for ...
متن کاملInteraction of the HOPS complex with Syntaxin 17 mediates autophagosome clearance in Drosophila
Homotypic fusion and vacuole protein sorting (HOPS) is a tethering complex required for trafficking to the vacuole/lysosome in yeast. Specific interaction of HOPS with certain SNARE (soluble NSF attachment protein receptor) proteins ensures the fusion of appropriate vesicles. HOPS function is less well characterized in metazoans. We show that all six HOPS subunits (Vps11 [vacuolar protein sorti...
متن کاملLAMP-2 is required for incorporating syntaxin-17 into autophagosomes and for their fusion with lysosomes
Autophagy is an evolutionarily conserved process used for removing surplus and damaged proteins and organelles from the cytoplasm. The unwanted material is incorporated into autophagosomes that eventually fuse with lysosomes, leading to the degradation of their cargo. The fusion event is mediated by the interaction between the Qa-SNARE syntaxin-17 (STX17) on autophagosomes and the R-SNARE VAMP8...
