Abstract

Yin Yang 1 protein (YY1) is a multifunctional transcription factor with ability to initiate, activate and repress transcription. The YY1 contains four C2H2-type zinc-finger motifs in C-terminus domain. N-terminus domain exhibits properties of an intrinsically disordered region. In this thesis, the effect of the addition exogenous factors on conformation of the full length protein and its N-terminal domain was analyzed. The influence of low-molecule osmolytes (glucose, glycerol, sucrose); TFE (the inducer of secondary structures creation) and macromolecules (Ddextran 40, Dextran 70 and Ficoll 70), used as crowding agents was examined.. The analysis of changes in the conformation of the main polypeptide chain was performed by using measureme...
