Mitochondria exist as an organellar network within most eukaryotic organisms, and are critical to biochemical energy production and cellular stress response. Mitochondrial bioenergetic function is directly linked to the complex morphological state of its network, existing in a balance of fusion (interconnected state) or fission (fragmented state). The optic atrophy-1 (OPA1) protein plays a major role in regulating mitochondrial inner membrane fusion, whereas the OMA1 metallopeptidase is highly involved in the degradation of the OPA1 protein, thus contributing to its fragmented state. Cellular stress such as a disruption in mitochondrial membrane potential activates OMA1 cleavage of OPA1. However, our data …
