**Background of Recombinant Human Thioredoxin-1 (Txn1) Protein**
Thioredoxin-1 (Txn1), a 12-kDa redox-active protein, is a key member of the thioredoxin family, widely expressed in humans. It plays a critical role in maintaining cellular redox homeostasis by regulating oxidative stress through its conserved Cys-Gly-Pro-Cys active site, which facilitates the reduction of disulfide bonds in target proteins. Txn1 interacts with thioredoxin reductase (TrxR) and NADPH to form a major antioxidant system, protecting cells from reactive oxygen species (ROS)-induced damage. Beyond its antioxidant function, Txn1 modulates signaling pathways, including apoptosis, inflammation, and cell proliferation, by interacting with proteins like ASK1 and NF-κB.
Recombinant human Txn1 protein is produced using *E. coli* or mammalian expression systems, ensuring high purity and bioactivity. Its engineered form often includes tags (e.g., His-tag) for simplified purification and detection. Recombinant Txn1 is indispensable in studying oxidative stress-related diseases (e.g., cancer, neurodegenerative disorders), drug development, and as a stabilizing agent for proteins prone to oxidation. Additionally, its anti-inflammatory and cytoprotective properties make it a therapeutic candidate for conditions like rheumatoid arthritis and ischemic injury. Research continues to explore its roles in aging, immune regulation, and metabolic diseases.
