Tomasz Kantyka, PhD
The scientific interests in our research group are focused on posttranslational modifications (PTMs) of proteins and peptides, which coincide with infection, inflammation and development of civilization-related diseases. The underlying hypothesis is that PTMs impact the structure and activity of proteins and bioactive peptides. Our aim is to correlate PTMs with observed activity and structural changes in the pathophysiological context in the effort to delineate mechanisms of diseases development and to identify novel potential therapeutic targets. Although our focus is on basic research, we always keep our sight on the pathophysiological importance of our findings and their applicability for translational developments.
Research techniques and equipment
As a whole, the research group has a broad experience in expression and purification of recombinant and native human and bacterial proteins, their biochemical characterization, PTM analysis, including effects on biological functions of peptides and proteins. The core of the laboratory machine park encompasses several FPLC and HPLC chromatography systems, Seismos NT.X Instrument from NanoTemper Technologies, which offers the Surface Acoustic Wave (SAW) method to measure binding kinetics and conformational changes, and microscale thermophoresis (MST) analyzers, including Monolith NT.115 and Monolith NT.FreeLabel (both from NanoTemper Technologies). Our research embraces many collaborators, local (WBBiB UJ, Collegium Medicum UJ, Institute of Pharmacology, PAN), national (Wroclaw Polytechnic, Gdansk University) and international (Bremen, Barcelona, Aarhus, Brno and many others), both academic and translational (Cortexyme, Inc., USA and Fraunhofer Institute, Germany) creating a truly interdisciplinary and international group very well linked, with high potentials to carry out ambitious research projects.
