Predicted to enable FAD binding activity; flavin-linked sulfhydryl oxidase activity; and protein disulfide isomerase activity. Predicted to be involved in extracellular matrix assembly; negative regulation of macroautophagy; and protein folding. Located in extracellular space. Is expressed in several structures, including alimentary system; cardiovascular system; nervous system; respiratory system; and skin. Used to study VACTERL association. Orthologous to human QSOX1 (quiescin sulfhydryl oxidase 1). [provided by Alliance of Genome Resources, Apr 2022]
