TrxR2 Rabbit Polyclonal Antibody

Thioredoxin reductase 2 (TXNRD2) Homo sapiens This gene encodes a member of the class I pyridine nucleotide-disulfide oxidoreductase family. The encoded protein is a selenocysteine-containing flavoenzyme that maintains thioredoxins in a reduced state, thereby playing a key role in regulating the cellular redox environment. Mammals have three related thioredoxin reductases. This gene encodes a mitochondrial form important for scavenging of reactive oxygen species in mitochondria. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Sep 2013], catalytic activity:Thioredoxin + NADP (+) = thioredoxin disulfide + NADPH., cofactor:FAD., function:Maintains thioredoxin in a reduced state. Implicated in the defenses against oxidative stress. May play a role in redox-regulated cell signaling., miscellaneous:The active site is a redox-active disulfide bond. The selenocysteine residue is essential for enzymatic activity., sequence caution:Translated as Sec., similarity:Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family., subunit:Homodimer., tissue specificity:Highly expressed in the prostate, ovary, liver, testis, uterus, colon and small intestine. Intermediate levels in brain, skeletal muscle, heart and spleen. Low levels in placenta, pancreas, thymus and peripheral blood leukocytes. According to PubMed:10608886, high levels in kidney, whereas according to PubMed:9923614 levels are low.
