Endogení elektrické pole a organizace živé hmoty
Pokorný, Jiří ; Hašek, Jiří ; Jelínek, František
Endogenous electromagnetic field with strong electric component generated by polar structures, in particular by microtubular structures, has important function in charge and mass transport which conditions biological activity. The Wiener-Lévy process is used for analysis of the transport with deterministic and random (thermal) components whose ratio may be important for biological function. Electric field can have dominant effect on directed transport at short and medium distances up to about 0.1 µm.
Experimentální zkoumání elektromagnetické aktivity kvasinkových buněk na milimetrových vlnách
Jelínek, František ; Hašek, Jiří ; Šaroch, Jaroslav ; Pokorný, Jiří
The direct detection of oscillations in biological cells may deliver strong evidence for Fröhlich´s theory of coherent excitation in biological systems. Some results of measurement at millimeter waves published in the literature are mentioned. A laboratory equipment for the measurement of mm-waves excitations in yeast cells is described. The measurement system is controlled by computer and measured data are stored in the computer memory for evaluation. Some results of the evaluation are given.
RPG1P affects reassembly of microtubules in saccharomyces cerevisiae
Špryngar, Martin ; Janatová, Ivana ; Hašek, Jiří
RPG1/TIF32, the essential gene of Saccharomyces cerevisiae, incodes the subunit of the translation initiation factor leF3 displaying an interesting connection between the translation machinery and cytoskeleton in S.cerevisiae.
C-terminus of sla2p is sufficient for interaction with rpg1p in cytotrap system in saccharomyces cerevisiae
Janda, Filip ; Janatová, Ivana ; Jirásková, Alena ; Hašek, Jiří
The gene RPG1/TIF32 of Saccharomyces cerevisiae encodes the largest subunit of translation initiation factor elF3.
RPG1/TIF32P mediates formation of stress granules
Hašek, Jiří ; Špryngar, Martin ; Janatová, Ivana
Rpg1/Tif32p is the essential subunit of the translation initiation factor 3 core complex (elF3) of Saccharomyces cerevisiae.
Schizosaccharomyces pombe RPG1 protein causes G2/M delay in the cell cycle when overproduces in saccharomyces cerevisiae
Janatová, Ivana ; Koubek, Zdeněk ; Malínská, Kateřina ; Raková, Radka ; Hašek, Jiří
S. pombe rpg1 encodes a protein homologous to Rpg1p/Tif32p of S. cerevisiae, which is the large subunit of the translation initiation factorelF3 interacting with microtubules and actin functionally replace Rpg1p in deletion.
Vyhledávání jaderného transportinu faktoru ISW1 remodelujícího chromatin u Saccharomyces cerevisiae
Strádalová, Vendula ; Hašek, Jiří ; Janatová, Ivana
Several intragenously-tagged versions of the ISW1 gene were constructed to follow Isw1p localization either in living (GFP-fusions) or in fixed cells (c-Myc-fusions). The whole set of available importin mutants was transformed with vectors carrying an intragenously-tagged ISW1 gene. In the strains where the importins Kap120p, Nmd5p, Sxm1p, Kap114p, Los1p, Msn5p, Kap123p and Pdr6 were deleted, the Isw1p-GFP fusion regulated by the ISW1 promoter was localized always in the nucleus. This suggests that none from these importins is required for nuclear localization of Isw1p. The localization of the Isw1p-GFP in the mtr10-1 strain differed from that observed in all the other analyzed importin mutants. Our results indicate that Mtr10p could be a good candidate for Isw1p importin.
Rpg1p/eIF3a se spojuje s mitochondriemi v Saccharomyces cerevisiae
Hašek, Jiří ; Janatová, Ivana ; Špryngar, Martin ; Wolinski, H. ; Kohlwein, S. D.
RPG1/TIF32, the essential gene of Saccharomyces cerevisiae, encodes eIF3a subunit of the translation initiation factor 3. We show here that both temperature sensitive mutant of Rpg1 strongly differ in their distribution at permissive temperature, distribution of the Rpg1-1-GFP fusion is cytosolic, the fusion protein Rpg1-2-GFP was accumulated in large cytosolic aggregates. Using the life image analysis with confocal laser scanning microscope we found that these granules could be inherited to daughter cells and obviously associate with mitochondria.
