Analysis of C. necator genome changes after evolutionary adaptation
 Vojsovič, Matúš ; Šedrlová, Zuzana (oponent) ; Brázda, Václav (vedoucí práce)
The p53 protein is a transcription factor that belongs to the group of the tumour suppressor proteins. p53 functions include cell cycle regulation, interaction with DNA, and responses to damaged DNA that may lead to apoptosis or even senescence may occur. The theoretical part summarizes the latest information about the chemical structure and functions of the protein p53 and allosteric modifications that the p53 protein may possess in cells. It also describes selected methods of isolation and characterizes proteins. The aim of the experimental part was to isolate and characterize -isoforms of the p53 protein, which were isolated from the microorganism E.coli. Protein production was preceded by preparation and transformation of plasmids into production cells. From the production cells, 4 -isoforms of p53 were isolated by affinity chromatography, due to the polyhistidine anchor that the proteins contain. The isolated proteins were subsequently characterized by SDS-PAGE and western blotting. Moreover, the transactivation potential in the yeast system was monitored by luciferase assay under conditions involving the use of various culture media, as well as expressed or coexpressed under the inducible GAL1 promoter and the constitutive GPD promoter.
