The International Max Planck Research School for Chemical and Molecular Biology (IMPRS-CMB) is a collaboration between the Max Planck Institute of Molecular Physiology and three universities, the Technical University Dortmund (TU Dortmund), the Ruhr University Bochum (RUB) and the University of Duisburg-Essen (DUE).

All four institutes are located in the Ruhr Metropolitan Area of Germany, an extremely vibrant and culturally interconnected region. The same spirit is reflected in the science of our program: research groups, with different and often complementary approaches, combine their efforts to study at the molecular level basic cell physiology.

Below you can find all the research groups that are part of IMPRS-CMB, in alphabetical order. You can also search groups by name, topic or technique.

Research Interest
Cells need to cope with a multitude of stress conditions that relentlessly inflict damage to its most vital components. This includes insults to the DNA that threatens genome stability, damage of proteins that can then form toxic aggregates, or injury of whole organelles such as mitochondria and lysosomes that releases harmful components. Cells have developed sophisticated molecular responses to these stresses that maintain protein homeostasis and organelle function, and ensure genomic stability. We are interested in deciphering these responses and uncover how they counteract stress-induced cell death and aging-related degeneration, or maintain cell proliferation.

We have been working to understand how the ubiquitin-proteasome system governs these cellular stress responses with a recent focus on the role of autophagy and underlying mechanisms. The projects have relevance for understanding myodegenerative and neurodegenerative diseases such as amyotrophic lateral sclerosis and frontotemporal dementia, as well as for novel approaches to cancer therapy.  Our approaches are fluorescence microscopy of tissue culture models, gene silencing and editing, imaging-based small-scale screening, biochemical and proteomic analysis.
