Quiescin sulfhydryl oxidase 1 (QSOX1) is an enzyme that catalyzes disulfide bond formation by oxidizing two free sulfhydryl groups. QSOX1 consists of a thioredoxin (Trx) and an ERV (essential for respiration and viability)/ALR (augmenter of liver regeneration) domain which each contain CxxC motifs that work to bind to substrates and shuttle electrons to a flavin adenine dinucleotide (FAD) cofactor that accepts the electrons and reduces molecular oxygen to hydrogen peroxide. Investigation of the role of QSOX1 in cancer progression started when it was found at higher abundance in pancreatic ductal adenocarcinoma (PDA) patient plasma compared to healthy normal donor plasma. …
