The role of the WASH complex in endolysosomal homeostasis
 Beránková, Pavla ; Libusová, Lenka (advisor) ; Rösel, Daniel (referee)
The WASH (WASP and SCAR homologue) complex is an actin nucleation promoting factor essential for endosomal cargo sorting. Upon WASH complex depletion, endosomal cargoes are mislocalized and the endolysosomal system collapses. Here, we employed high-speed vesicle tracking and real-time rescue experiments to test the effect of WASH complex depletion on endolysosomal homeostasis. We found that large lysosome-like vacuoles emerge in knockout cell lines of individual WASH complex subunits, although the overall dynamics of the lysosomal network does not substantially change. Follow-up experiments revealed that the WASH complex does not act directly on the vacuoles during their rescue. Overall, the data indicate that the emergence of vacuoles in WASH complex knockouts is a secondary process that depends on the WASH complex indirectly.
