Thioredoxin/TXN Protein, Human
Based on 1 publication(s) in Google Scholar
Thioredoxin/TXN protein participates in multiple redox reactions, utilizing its active center dithiol for reversible oxidation and disulfide bond formation. It catalyzes important dithiol-disulfide exchange and plays a key role in S-nitrosylation of cysteine residues in response to intracellular nitric oxide. Thioredoxin/TXN Protein, Human is the recombinant human-derived Thioredoxin/TXN protein, expressed by E. coli , with tag free.
- Species: Human
- Source: E. coli

Biological Activity
Thioredoxin/TXN protein participates in multiple redox reactions, utilizing its active center dithiol for reversible oxidation and disulfide bond formation. It catalyzes important dithiol-disulfide exchange and plays a key role in S-nitrosylation of cysteine residues in response to intracellular nitric oxide. Thioredoxin/TXN Protein, Human is the recombinant human-derived Thioredoxin/TXN protein, expressed by E. coli , with tag free.
Thioredoxin/TXN Protein actively engages in diverse redox reactions, employing the reversible oxidation of its active center dithiol to form a disulfide bond, and catalyzes crucial dithiol-disulfide exchange reactions. Beyond its classical redox functions, Thioredoxin plays a pivotal role in the reversible S-nitrosylation of cysteine residues within target proteins, contributing to the cellular response to intracellular nitric oxide. Notably, it exerts regulatory control over caspase-3 activity by nitrosylating the active site cysteine of CASP3 in response to nitric oxide. Moreover, Thioredoxin demonstrates its influence on the FOS/JUN AP-1 DNA-binding activity in ionizing radiation cells, modulating AP-1 transcriptional activity through its oxidation/reduction status. Additionally, Thioredoxin is implicated in the augmentation of interleukin-2 receptor TAC (IL2R/P55) expression, highlighting its multifaceted role in cellular processes beyond redox regulation.
Measured by its ability to catalyze the reduction of insulin. The reaction leads to precipitation, which can be measured by absorbance at 650 nm and the specific activity is 5-11 A650/min/mg.

Product Properties
Lyophilized powder
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
