靶点详情

  • 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.

    6. High levels of QSOX1 RNA expression is associated with breast cancer. PMID: 23536962
    7. these studies suggest that QSOX1 is a predictive biomarker for luminal cancers and that it may be a useful target for elusive luminal B disease PMID: 23680167
    8. QSOX1 may be revealed as an important player in cancer detection and prognosis. Defining the mechanism(s) of QSOX1 activity in tumors and in in vivo models will provide important insights into how to target QSOX1 with anti-neoplastic agents. PMID: 24359107
    9. Examination of the unusual kinetics of QSOX1 toward cysteine and glutathione at low micromolar concentrations suggests that circulating QSOX1 is unlikely to significantly contribute to the oxidation of these monothiols in plasma PMID: 24468475
    10. QSOX1 may be involved in neuroblastoma differentiation and regression and may thus function as a biomarker for identifying risk groups for this neoplasm. PMID: 24704990
    11. QSOX1 is induced by hypoxic stimuli and identified that QSOX1 is a direct target of HIF-1. PMID: 24008827
    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
    13. QSOX1 is a potential new prognostic marker which may prove of use in the staging of breast tumours and the stratification of breast cancer patients. PMID: 23460839
    14. QSOX1 activity was required for incorporation of laminin into the extracellular matrix (ECM) synthesized by fibroblasts, and ECM produced without QSOX1 was defective in supporting cell-matrix adhesion. PMID: 23704371

    16. These results propose for the first time possible roles for QSOX1 in atherosclerosis. PMID: 22069028
    17. Taken together, our results suggest that the mechanism of QSOX1-mediated tumor cell invasion is by activation of MMP-2 and MMP-9. PMID: 21989104
    18. Data suggested that the C449-C452 motif was essential for the activity of human QSOX 1b; the C70-C73 motif was fundamental in electron transfer from thiol-containing substrate including reduced proteins, DTT, GSH. PMID: 21148546

    20. In the plasma peptidome of patients with ductal adenocarcinoma of the pancreas (DAP), a prominent peptide was identified from the QSOX1 parent protein. This peptide was present in 16 of 23 DAP patients and 4 of 5 patients with IPMN. PMID: 19795908
    21. Data show that the longer version of human QSOX1 protein (hQSOX1a) is a transmembrane protein localized primarily to the Golgi apparatus, and that hQSOX1a can act in vivo as an oxidase. PMID: 17331072
