Mitochondrial unfolded protein response

The mitochondrial unfolded protein response (UPRmt) is a cellular stress response related to the mitochondria. The UPRmt results from unfolded or misfolded proteins in mitochondria beyond the capacity of chaperone proteins to handle them. The UPRmt can occur either in the mitochondrial matrix or in the mitochondrial inner membrane. In the UPRmt, the mitochondrion will either upregulate chaperone proteins or invoke proteases to degrade proteins that fail to fold properly. UPRmt causes the sirtuin SIRT3 to activate antioxidant enzymes and mitophagy.
