ParkinPINK1 and OMA1 are known stress sensors activated by mitochondrial dysfunction.

Parkin , an E3 ubiquitin ligase, is recruited to the outer mitochondrial membrane through PINK1 phosphorylation, promoting mitochondrial degradation processes.

The study reveals that these stress-responsive systems control mitochondrial fusion under normal physiological conditions.
