The complex multimeric composition of factor VIII/von Willebrand factor.
We have analyzed the multimeric structure of factor VIII/von Willebrand factor in plasma by sodium dodecyl sulfate electrophoresis using gels of varying porosity and a discontinuous buffer system. Factor VIII/von Willebrand factor bands were identified by reaction with 125I-labeled affinity-purified antibody and subsequent autoradiography. In 1% agarose gels, normal plasma displayed a series of...
متن کاملTopography of the human factor VIII-von Willebrand factor complex.
Factor VIII circulates in noncovalent complex with von Willebrand factor (vWf). The topography of this complex was evaluated by fluorescence energy transfer using factor VIII subunits modified with N-(1-pyrenyl)maleimide (NPM; fluorescence donor) and vWf-derived fragments modified with 7-diethylamino-3-[4'-maleimidylphenyl]-4-methyl coumarin (CPM; fluorescence acceptor). Results from a previous...
متن کاملLectin activity of the coagulation factor VIII/von Willebrand complex.
The human coagulation factor VIII (FVIII) is essential in the intrinsic pathway of blood coagulation and circulates mainly as a non-covalently bound complex with the von Willebrand factor (VWF). This complex (FVIII/VWF) protects FVIII from degradation and cellular uptake, although no biological role has been identified yet for this complex. The FVIII/VWF complex was purified from a healthy dono...

15 صفحه اولvon Willebrand factor is a cofactor for thrombin-catalyzed cleavage of the factor VIII light chain.
The proteolytic activation of highly purified, heterodimeric porcine factor VIII and factor VIII-von Willebrand factor complex by thrombin was compared at I 0.17, pH 7.0, 22 degrees C. During the activation of factor VIII, heavy-chain cleavage is necessary to activate the procoagulant function, whereas light-chain cleavage is required to dissociate factor VIII from von Willebrand factor. The ki...
