Abstract

The project aims to define the role of the stress-activated peptidase OMA1 in the regulation of mitochondrial dynamics and function in response to stress and different metabolic demands. The project combines multiple proteomic approaches and experiments in cultured cells with in vivo approaches in mouse to unravel how OMA1 regulates the stress response of mitochondria and cell survival and to uncover novel functions of OMA1 within mitochondria.
