These proteins are thiol-disulfide oxidoreductases that use a glutathione-binding site and one or two active cysteines in their active site. This gene undergoes alternative splicing to produce multiple isoforms, one of which is ubiquitously expressed and localizes to mitochondria, where it functions in mitochondrial redox homeostasis and is important for the protection against and recovery from oxidative stress. Other isoforms, which have more restrictive expression patterns, show cytosolic and nuclear localization, and are thought to function in cellular differentiation and transformation, possibly with a role in tumor progression.

Involved in response to hydrogen peroxide and regulation of apoptosis caused by oxidative stress. Acts as a very efficient catalyst of monothiol reactions because of its high affinity for protein glutathione-mixed disulfides. Can receive electrons not only from glutathione (GSH), but also from thioredoxin reductase supporting both monothiol and dithiol reactions. Efficiently catalyzes both glutathionylation and deglutathionylation of mitochondrial complex I, which in turn regulates the superoxide production by the complex. Overexpression decreases the susceptibility to apoptosis and prevents loss of cardiolipin and cytochrome c release. {ECO:0000269|PubMed:11297543, ECO:0000269|PubMed:14676218, ECO:0000269|PubMed:15328416, ECO:0000269|PubMed:15649413}. |Glutaredoxin| |arsenate reductase (glutaredoxin) activity| |glutathione disulfide oxidoreductase activity| |DNA protection| |response to redox state| |cellular response to oxygen radical| |cellular response to superoxide| |response to superoxide| |response to oxygen radical| |protein disulfide isomerase activity| |protein disulfide oxidoreductase activity| |2 iron, 2 sulfur cluster binding| |glutathione metabolic process| |cell redox homeostasis| |electron transfer activity| |response to hydrogen peroxide| |cellular response to reactive oxygen species| |response to temperature stimulus| |electron transport chain| |response to reactive oxygen species| |cellular modified amino acid metabolic process| |cellular response to oxidative stress| |cellular response to extracellular stimulus| |aging| |response to antibiotic| |cellular response to external stimulus| |sulfur compound metabolic process| |mitochondrial matrix| |neuronal cell body| |response to oxidative stress| |dendrite| |generation of precursor metabolites and energy| |cofactor metabolic process| |response to toxic substance| |peptide metabolic process| |response to extracellular stimulus| |response to inorganic substance| |intracellular membrane-bounded organelle| |DNA metabolic process| |cellular amide metabolic process| |cellular homeostasis| |apoptotic process| |oxidation-reduction process| |response to drug| |programmed cell death| |cellular response to oxygen-containing compound| |cell death| |response to abiotic stimulus| |mitochondrion| |response to oxygen-containing compound| |homeostatic process| |cellular response to stress| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp279|D-Fructose 10000μM R06 exp279]]|-2.53| |[[:results:exp52|Ribavirin 10μM R01 exp52]]|-1.77| |[[:results:exp445|∆-9-Tetrahydrocannabinol 30μM R08 exp445]]|1.94| |[[:results:exp430|Rifampicin 30μM R08 exp430]]|1.96| No correlation found to any other genes in chemogenomics.
