Opis

General description

Cloned from Jurkat cell cDNA. Identical to the ADF/Trx (GenBank^® Accession Number X77584) and the thioredoxin from human placenta (GenBank^® Accession Number AF085844).

Thioredoxin (TXN) is a 12 kDa ubiquitous protein. The gene is located on human chromosome 9q31.3. TXN is mainly located in the cytoplasm.Thioredoxin contains a redox-active dithiol in the active site. Itexists in several forms, the most prevalent ones being the cytosolic (TRX1) andmitochondrial (TRX2) forms.[1]

Application

Thioredoxin human can be used for in vitro thioredoxin assay.[2] The product can also be used for assessing Thioredoxin reductase (TRXR) enzyme activity.[3]

Thioredoxin human has been used:

• in mitogen-activated protein kinase kinase 4 (MKK4) in vitro kinase assay
• to study its role in transcription regulation, RNA processing and nuclear pore function in human cells
• in proteomics identification of Trx1 reduction target proteins from the hearts of cardiac specific transgenic (Tg)-Trx1 mice

Biochem/physiol Actions

Human Thioredoxin is a recombinant, N-terminal histidine tagged protein. The product induces proliferation in lymphoid cells, fibroblasts as well as in numerous human solid tumor cell lines.[4]The product also stimulates growth in normal as well as leukemic B cell,[5] modifies the transcriptional activity of AP-1[6]and inhibits the apoptosis signal-regulating kinase 1 (ASK1).[7]Thioredoxin (TRX) plays a role in protecting the cells fromelectrophiles, a cytotoxic agent.[1]

Mediates the reduction of disulfide bonds in proteins.

Thioredoxin (TXN) has disulfide-reducing activity. It acts as a cytokine to reduce inflammation. TXN functions as a scavenger for reactive oxygen intermediates (ROIs), which are produced in various oxidative stress. Thioredoxin induces cellular proliferation to decrease oxidative stress. TXN is a prognostic biomarker for various cancers, such as lung, pancreatic and hepatocellular carcinoma. It contributes to protein reduction, tissue development and redox regulation.

Other Notes

One unit will cause a ΔA₆₅₀ of 1.0 in 1 min at 25 °C in the insulin reduction assay.
