1 This functional difference may be attributed to thiols exposed on the surface of plasma-type VWF multimers, but not on ULVWF multimers. Sulfhydryl Compounds von Willebrand factor Homo sapiens
2 Shear stress induces the exposed thiols to form disulfide bonds between laterally apposed plasma-type VWF multimers, leading to enhanced VWF binding to platelets. Sulfhydryl Compounds von Willebrand factor Homo sapiens
3 Shear stress induces the exposed thiols to form disulfide bonds between laterally apposed plasma-type VWF multimers, leading to enhanced VWF binding to platelets. Sulfhydryl Compounds von Willebrand factor Homo sapiens
4 OBJECTIVES: We tested a hypothesis that ADAMTS-13 has a disulfide bond reducing activity that regulates shear-induced thiol-disulfide exchange of VWF. Sulfhydryl Compounds von Willebrand factor Homo sapiens
5 RESULTS: ADAMTS-13 contains a disulfide bond reducing activity that primarily targets disulfide bonds in plasma-type VWF multimers induced by high shear stress or formed with thiol beads, but not disulfide bonds in native multimeric structures. Sulfhydryl Compounds von Willebrand factor Homo sapiens
6 Cysteine thiols targeted by this activity are in the VWF C-domain and are known to participate in shear-induced thiol-disulfide exchange. Sulfhydryl Compounds von Willebrand factor Homo sapiens
