FACT Protein Complex (image) Lomonosov Moscow State University Share Print E-Mail Caption This is an image of the functioning of FACT protein complex. FACT protein complex is a chaperon of histones, i.e. a factor that as a rule stabilizes nucleosome. However, the presence of a small DNA-binding protein Nhp6 radically changes the function of FACT by untwisting the nucleosome. This change in activity was demonstrated both for yeast and human FACT.
