Research
We use X-Ray crystallography in combination with biochemical and biophysical methods to provide the molecular mechanisms of protein interactions implicated in the regulation of the microtubule cytoskeleton. The elucidation and further exploration of these interactions at atomic resolution are pivotal to both basic and applied research in this field, and have important implications for the treatment of cancer and neurodegenerative diseases.
Our research activities are dedicated to the structural analysis of tubulin interactions with microtubule-targeting agents (MTAs). MTAs like taxol efficiently block cell entry into mitosis and are among the most potent chemotherapeutic drugs used for the treatment of different types of cancers. Despite the importance of MTAs for medical and basic research applications, their molecular mechanisms of action often remain elusive. Using X-ray crystallography and cryo EM we study the mechanisms of action of diverse MTAs by determining their structures in complex with tubulin and microtubules to high resolution.
Our research portfolio further covers the structural analysis of tubulin-complexes with various modulatory proteins. As part of the EU-funded Innovative Training Network TubInTrain https://www.tubintrain.eu, we study the role of microtubules in neurotoxicity and neurodegenerative disorders. In particular, we investigate different strategies for tuning tubulin/MTs dynamics and interactions with selected proteins and ligands at the atomic level, aiming at providing new relevant indications for the future design of effective drugs or novel therapeutic interventions.
