Background Information

QSOX1(Sulfhydryl oxidase 1) catalyzes the oxidation of sulfhydryl groups in peptide and protein thiols to disulfides with the reduction of oxygen to hydrogen peroxide.It has two isoforms with the molecular weight of 67 kda and 83 kDa,respectively. It is detected a band of 95 Kda in HT1080 cell lines (PMID:17331072).Isoform 1 is expressed on golgi apparatus membrane and isoform 2 is secreted (PMID:10708601). The isoform1(QSOX1a) is the full length of QSOX1, approximately 78 kd; and the isoform2(QSOX1b) is the splicing form, approximately 62kd(PMID:14633699; 2496424). QSOX1 is highly expressed in tumor cell lines but is not expressed in adjacent normal cells (PMID:21989104).
