Major Research Interests:
The focus of our group is the biogenesis of mitochondrial proteins. A small number of these proteins is synthesized on mitochondrial ribosomes. Owing to their hydrophobic nature, mitochondrial translation products are inserted into the inner membrane in cotranslational process which relies on the tight membrane binding of mitochondrial ribosomes. Most mitochondrial proteins are synthesized as precursors in the cytosol. How these precursors reach the mitochondrial outer membrane, how they are prevented from folding and aggregation and how they are degraded if their import fails are current questions in the lab.
