Function

Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions (PubMed:17182577, PubMed:19032234, PubMed:2176490). 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 (PubMed:16408020, PubMed:17606900). 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 (PubMed:11118054, PubMed:9108029). ADF augments the expression of the interleukin-2 receptor TAC (IL2R/P55).

Activity summary

Thioredoxin (TRX) also known as TXN or Trx is a small redox protein with a molecular mass of approximately 12 kDa. It acts as an oxidoreductase enzyme facilitating the reduction of other proteins by cysteine thiol-disulfide exchange. Thioredoxin is ubiquitously expressed across various tissues indicating its function in a broad range of cellular activities. The protein comprises an active site with a conserved Cys-Gly-Pro-Cys sequence critical for its reducing activity.

Biological function summary

Thioredoxin influences cellular redox homeostasis and plays direct roles in regulating cell growth and apoptosis. It participates as a major reductant in cells influencing transcription factors and enzymatic activities that depend on thiol-disulfide exchanges. Thioredoxin can interact with other components like thioredoxin reductase and NADPH to form the thioredoxin system a powerful antioxidant defense mechanism. Diseases typically arise from abnormal regulation of this system highlighting its influence on cellular survival and proliferation.

Pathways

Thioredoxin integrates into significant signaling and metabolic processes. It is an important player in the cellular response to oxidative stress and participates in signaling pathways such as the MAPK and apoptosis pathways. In these pathways thioredoxin reduces the oxidative stress transcription factor AP-1 influencing cell fate decisions. Its interaction with thioredoxin-interacting protein (TXNIP) further modulates cellular responses to oxidative environments.

Associated diseases and disorders

Altered thioredoxin activity associates with cancer and neurodegenerative diseases. Its overexpression links to tumor progression where it promotes survival and resistance to apoptosis. Additionally in the context of neurodegenerative disorders thioredoxin’s interaction with amyloid-beta peptides implicates it in Alzheimer’s disease by mitigating oxidative stress damage. Through these conditions its role as a protector against oxidative stress remains pivotal.

    Immunoprecipitation - Anti-Thioredoxin / TRX antibody (ab26320)

    Thioredoxin / TRX was immunoprecipitated using 0.5mg Hela whole cell extract, 5μg of Rabbit polyclonal to Thioredoxin / TRX and 50μl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40μl SDS loading buffer and incubated for 10min at 70°C; 10μl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab26320.

CHO cells co-transfected with plasmids encoding GFP and a mutated form of human thioredoxin which does not enter the nucleus, and labelled using ab26320 (1/1000) and Alexa 568 (1/300). Panel [A] demonstrates GFP immunoreactivity. [B ]thioredoxin immunoreactity; many of the same cells are immunoreactive for both GFP and thioredoxin. Panel [D] thioredoxin primary antibody was omitted, hence there is no immunoeactivity.
