  • 功能：
    Catalyzes the oxidation of sulfhydryl groups in peptide and protein thiols to disulfides with the reduction of oxygen to hydrogen peroxide. Plays a role in disulfide bond formation in a variety of extracellular proteins. In fibroblasts, required for normal incorporation of laminin into the extracellular matrix, and thereby for normal cell-cell adhesion and cell migration.

    12. Data suggest that isoenzyme QSOX1A is secreted from mammalian cells despite transmembrane domain; QSOX1A is cleaved at internal sites and processed within Golgi apparatus to yield soluble enzyme that forms dimer upon cleavage of C-terminal domain. PMID: 23713614
