Protein-protein interactions (PPIs) play a crucial role in almost all biological processes. Many proteins require a number of dynamic interactions with other proteins and/or biomolecules to function. Proteomic studies have suggested that human protein-protein interactome consists of several hundred thousands of protein complexes. A detailed insight into these PPIs is essential for a complete understanding of the processes mediated by these protein complexes. Because many PPIs are involved in disease-related signaling pathways, such PPIs are important targets for pharmaceutical interventions, especially in situations where a more conventional target (e.g. the active site of an enzyme, the binding site of a receptor) cannot be used. This doctoral thesis focuses on 14-3-3 proteins, a family of eukaryotic adaptor and scaffolding proteins involved in the regulation of many signaling pathways. The 14-3-3 proteins function as interaction hubs and critical regulators of many enzymes, receptors and structural proteins. The main aim was to structurally characterize selected 14-3-3 protein complexes and investigate their stabilization by small molecule compounds. Using combination of protein crystallography, differential scanning fluorimetry, fluorescence polarization and analytical ultracentrifugation, the...
