The mitochondrial outer membrane plays a crucial role in the biogenesis, inheritance and dynamics of the organelle and forms the functional and signaling link between mitochondria and the rest of the eukaryotic cell. This membrane contains a diverse set of proteins that are synthesized in the cytosol and harbor signals that are essential for their subsequent import into mitochondria. We investigate the molecular mechanisms by which the various mitochondrial outer membrane proteins are targeted to mitochondria, inserted into the outer membrane and assembled into functional complexes within the membrane. In addition, we study the mechanisms and components that regulate lipids homeostasis in mitochondria. For our studies we use both yeast and mammalian tissue cultures as experimental systems.
We are looking for highly motivated candidates holding a Master degree in biology, biochemistry, molecular medicine, cell biology, biophysics, or a similar program.
The PhD students will join our DFG funded Research Training Group (RTG):
The aim of our RTG is to achieve comprehensive understanding of the structure, function, regulation, and biogenesis of the mitochondrial outer membrane. We employ a multidisciplinary approach including disease models, molecular cell biology, proteomics, biotechnology, and biophysics.

Mitochondria are an ancient cooperation of our nucleated cells and incorporated bacteria. They provide us with energy but are no longer independently viable with many of their proteins having been exported to the nuclear genome. The re-import of these proteins is crucial for proper function. Doron Rapaport and co-workers of the IFIB discovered a new way for a group of proteins to be inserted into the mitochondrial membrane. These findings help explain how mitochondria are correctly assembled and maintained, a process that is essential to avoid diseases. (Scientific paper) (Press release German)
