Mitochondrial proteostasis and protein quality control

Mitochondria are essential organelles well known for their role in ATP synthesis, multiple metabolic pathways or programmed cell death. They form a dynamic elongated network and are integrated into the cellular signalling network. To fulfill their various functions mitochondria have to build and maintain a complex proteome of more than 1000 different proteins. The vast majority of these mitochondrial proteins is imported post-translationally into the organelle and requires proteolytic processing to mature into functional and stable proteins. We are interested in the proteases that perform this processing and subsequent quality control of the incoming precursors.

Maintenance of the mitochondrial proteome can also be challenged by stress or disease mutations and the cell protects mitochondrial proteostasis by eliciting transcriptionally responses ("mitochondrial unfolded protein response"). We are investigating how disease mutations affect mitochondrial proteostasis, how the cell is sensing these imbalances and how mitochondria are molecularly remodeled to cope with and overcome stress in form of toxic protein aggregates.
