Recombinant expression of RhoA protein with affinity tag.
Filipová, Barbora ; Novák, Petr (advisor) ; Šulc, Miroslav (referee)
The rate of intestinal infections associated with antibiotics has been rising steeply. Virulent toxins of C. difficile, Yersinia and many other bacteria target the RhoA protein. The protein is a GTPase involved in signalling pathways, its major function being the regulation of the actin cytoskeleton. The above mentioned toxins render this protein non- functional, which may lead up to a fatal destruction of the cell. The present diagnostic methods of these infections are insufficient. The use of protein chips and mass spectrometry to detect any RhoA protein modifications seems to provide a feasible method of determining these intestinal bacterial diseases. Therefore the purpose of this study is to use recombinant methods to prepare the desired RhoA protein with a bound affinity probe which will serve to its immobilisation on a biochip. The thus prepared protein will be subsequently used to diagnose the previously described diseases. In Czech.
