Triplet structure of human von Willebrand factor.
Human von Willebrand factor (hp-vWF) is a high-molecular- mass protein found in plasma as a series of multimers. It consists of subunits comprising 2050 amino acids linked by disulphide bonds into multimers of various size ranging in molecular mass up to greater than 10000kDa. Partial proteolysis at position Tyr842-Mer843 of the subunit [Dent et al. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 6306...
متن کاملStructure and function of von Willebrand factor.
von Willebrand factor (VWF) is a long plasma protein that contains many domains and each domain has its own function. VWF exists in a multimeric form and performs varieties of functions in the human body, including thrombus formation and blood coagulation. The crystal structures of three subdomains are known, and, interestingly, all three domains share identical three-dimensional fold with α-β-...
متن کاملA variant of von Willebrand's disease characterized by recessive inheritance and missing triplet structure of von Willebrand factor multimers.
A 10-yr-old girl had bleeding symptoms of moderate severity; her mother and maternal aunt had milder bleeding symptoms, and other members of the kindred were asymptomatic. In the child, factor VIII coagulant activity (VIII:C) and von Willebrand factor antigen (vWF:Ag) were normal, ristocetin cofactor very low, and the bleeding time (BT) markedly prolonged. These values were normal in the rest o...
متن کاملZebrafish von Willebrand factor.
von Willebrand factor (vWF) is a large protein involved in primary hemostasis. A dysfunction in this protein or an insufficient production of the protein leads to improper platelet adhesion/aggregation, resulting in a bleeding phenotype known as von Willebrand disease (vWD). To gain a better understanding of vWF interactions in vivo, the use of zebrafish as a model is ideal because of the trans...
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...
