Mitochondria are the cell’s power stations; they transform the energy stored in nutrients for use by cells. If this function is disturbed, mitochondrial diseases can develop that often affect organs that have a high metabolism, like the brain or the heart. The research labs at the University of Freiburg led by Prof. Dr. Chris Meisinger and Dr. Nora Vögtle successfully mapped the landscape of proteins in the subcompartments of mitochondria for the first time. They published their research in the scientific journal Nature Communications.
