Previous GeneCards Identifiers for TXN Gene
The protein encoded by this gene acts as a homodimer and is involved in many redox reactions. The encoded protein is active in the reversible S-nitrosylation of cysteines in certain proteins, which is part of the response to intracellular nitric oxide. This protein is found in the cytoplasm. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]
GeneCards Summary for TXN Gene
TXN (Thioredoxin) is a Protein Coding gene. Diseases associated with TXN include Adult T-Cell Leukemia and Myocarditis. Among its related pathways are Innate Immune System and Gene Expression. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity, acting on a sulfur group of donors, disulfide as acceptor. An important paralog of this gene is TXNDC2.
UniProtKB/Swiss-Prot for TXN Gene
Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. Plays a role in the reversible S-nitrosylation of cysteine residues in target proteins, and thereby contributes to the response to intracellular nitric oxide. Nitrosylates the active site Cys of CASP3 in response to nitric oxide (NO), and thereby inhibits caspase-3 activity. Induces the FOS/JUN AP-1 DNA-binding activity in ionizing radiation (IR) cells through its oxidation/reduction status and stimulates AP-1 transcriptional activity.
