uality control compartment (IMiQ). Only minor amounts of endogenous proteins coaggregated with IMiQ deposits and neither resolubilization nor degradation by the mitochondrial protein quality control system were observed. The single IMiQ aggregate deposit was not transferred to daughter cells during cell division. Detoxification of aggregates via IMiQ formation was highly dependent on a functional mitochondrial fission machinery. We conclude that the formation of an aggregate deposit is an important mechanism to maintain full functionality of mitochondria under proteotoxic stress conditions.
