Dynamics of yeast plasma membrane domains
Oláhová, Dominika ; Zahumenský, Jakub (advisor) ; Vopálenská, Irena (referee)
Plasmatic cellular mebrane consists of specialized domains which differ in shape, function and size. This compartmentalization allows cells to coordinate and separate a large number of diverse processes. Disorders of cell organization at the level of membrane domains are increasingly associated with the expansion of pathological disorders. Microdomains also play a role in the virulence of pathogenic organisms, e.g. some types of yeast. One of the best described microdomains of the yeast plasma membrane is the MCC (membrane compartment of arginine permease Can1), which is stabilized by a protein complex called the eisosome. The composition of the MCC/eisosome is described in detail, the dynamics of the individual components in the basal state (i.e. without stress) has not yet been described. The aim of this thesis is to summarize current knowledge about the dynamics of the proteins of this microdomain and its relationship with other domains of cell membranes through a detailed review of the available literature. And at the same time by using the advanced fluorescence method FRAP (fluorescence recovery after photobleaching) to show in my own experiment that in the basal state there is an exchange of individual Nce102 molecules in the MCC/eisosome microdomain. Key words: yeast, plasma membrane,...
