Recombinant human DSU protein, often associated with disulfide bond formation or isomerization, belongs to a class of proteins critical for maintaining proper protein folding and stability. DSU (Disulfide-related Structural Unit) is hypothesized to function as a disulfide isomerase or chaperone, facilitating correct cysteine pairing in nascent polypeptides, particularly in the endoplasmic reticulum. Produced via recombinant DNA technology, it is typically expressed in prokaryotic (e.g., *E. coli*) or eukaryotic systems to ensure proper post-translational modifications. Researchers employ recombinant DSU to study its role in cellular processes like oxidative protein folding, quality control, and redox signaling. Its applications extend to investigating diseases linked to misfolded proteins, such as neurodegenerative disorders or cancer, where disrupted disulfide bonding contributes to pathogenesis. Additionally, recombinant DSU serves as a tool for industrial biotechnology, aiding in the production of complex biologics requiring precise disulfide connectivity. Structural studies using recombinant DSU have revealed conserved thioredoxin-like domains, catalytic motifs (e.g., CXXC), and substrate-binding regions, offering insights into its mechanism. Despite its significance, DSU's full physiological interactome and regulatory pathways remain under exploration, highlighting its potential as a therapeutic target or diagnostic marker in protein-misfolding pathologies.
