Structure means mode of existence, which determines the function. Laboratory of Structural Proteomics studies structural and biophysical transformation of proteins involved in neurodegenerative processes and structural principles of antibody effects on disease-modified proteins. Our focus is aimed at proteins with a high degree of structural disorder, so called intrinsically disordered proteins (IDPs), which are often involved in devastating human illnesses, namely tau protein (Alzheimer’s disease), synuclein (Parkinson disease) and prion protein (spongioform encephalopathy).

We employ structural biology tools (X-ray crystallography) corroborated with dynamic biophysical methods of protein structure analysis (surface plasmon resonance, light scattering, molecular spectroscopy, mass spectrometry) and supported by molecular modeling in silico.

We analyse recombinant forms of tau proteins and their interactions with structure-specific monoclonal antibodies.
