CC -!- FUNCTION: Glutathione-dependent oxidoreductase that facilitates the CC maintenance of mitochondrial redox homeostasis upon induction of CC apoptosis by oxidative stress. Involved in response to hydrogen CC peroxide and regulation of apoptosis caused by oxidative stress. Acts CC as a very efficient catalyst of monothiol reactions because of its high CC affinity for protein glutathione-mixed disulfides. Can receive CC electrons not only from glutathione (GSH), but also from thioredoxin CC reductase supporting both monothiol and dithiol reactions. Efficiently CC catalyzes both glutathionylation and deglutathionylation of CC mitochondrial complex I, which in turn regulates the superoxide CC production by the complex. Overexpression decreases the susceptibility CC to apoptosis and prevents loss of cardiolipin and cytochrome c release CC (By similarity). {ECO:0000250}. CC -!- ACTIVITY REGULATION: The 2Fe-2S present in the homodimer leads to CC inactivation of the enzyme. The 2Fe-2S may serve as a redox sensor: the CC presence of one-electron oxidants or reductants leading to the loss of CC the 2Fe-2S cluster, subsequent monomerization and activation of the CC enzyme (By similarity). {ECO:0000250}. CC -!- SUBUNIT: Monomer; active form. Homodimer; inactive form. The homodimer CC is probably linked by 1 2Fe-2S cluster (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250}. CC -!- SIMILARITY: Belongs to the glutaredoxin family. {ECO:0000305}.
