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.
Membraneless organelles in eukaryotic cells
Beránková, Pavla ; Libusová, Lenka (advisor) ; Bařinka, Cyril (referee)
Membraneless organelles (MLOs) are a newly described type of cellular compartments. They consist of protein and nucleic acid molecules that undergo liquid-liquid phase separation (LLPS). MLOs are able to fulfill unique biological roles, because they are highly dynamic and their composition can be effectively regulated. Composition and function of these formations are swiftly being elucidated. The work summarizes the basic principles of LLPS in living organisms and further focuses on several types of MLOs functionally connected to microtubules (MTs). Their recurrent feature is the ability to nucleate MTs. This eventual role corresponds well with their high temporal and spatial dynamics.
