Function Catalyzes the oxidation of sulfhydryl groups in peptide and protein thiols to disulfides with the reduction of oxygen to hydrogen peroxide. May contribute to disulfide bond formation in a variety of secreted proteins (By similarity). {ECO:0000250}.
Subcellular Localization Isoform 1: Golgi apparatus membrane {ECO:0000250}; Single-pass membrane protein {ECO:0000250}.Isoform 2: Secreted. Note=Found in the extracellular medium of quiescent cells but not in proliferating cells.Isoform 3: Secreted. Note=Found in the extracellular medium of quiescent cells but not in proliferating cells.Isoform 4: Secreted. Note=Found in the extracellular medium of quiescent cells but not in proliferating cells.
