Research Interest
The mitochondrial outer membrane contains a diverse set of proteins including enzymes, pore-forming proteins, regulators of programmed cell death, and those that control the morphology of the organelle.
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. In addition we aim to understand how proteins that are mistargeted to mitochondria are recognized as such and subsequently removed. We further study the exchange of lipids between mitochondria and other cellular compartments and lipid trafficking within mitochondria. For our studies we use both yeast and mammalian tissue cultures as experimental systems and employ a variety of biochemical, molecular cell biology and genetics assays.
