Thioredoxin/TXN Protein, Human (Solution)

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 (Solution) is the recombinant human-derived Thioredoxin/TXN protein, expressed by E. coli , with tag free. The total length of Thioredoxin/TXN Protein, Human (Solution) is 105 a.a., with molecular weight of ~14 kDa.

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.
