Entrez Gene Summary for TXNRD2 Gene

  • 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]

GeneCards Summary for TXNRD2 Gene

TXNRD2 (Thioredoxin Reductase 2) is a Protein Coding gene. Diseases associated with TXNRD2 include thyroid hormone resistance and generalized resistance to thyroid hormone. Among its related pathways are PAK Pathway and Glucose / Energy Metabolism. GO annotations related to this gene include flavin adenine dinucleotide binding and thioredoxin-disulfide reductase activity. An important paralog of this gene is TXNRD3.
