Activation of factor VIII by factor IXa.
Thrombin causes an increase in factor VIII coagulant (VIII:C) activity, which is followed by a decay of VIII:C activity to below baseline levels. It has been suggested that a similar interaction of trace amounts of thrombin and factor VIII is a necessary prerequisite before factor VIII can participate in the coagulation cascade. In the current study, factor IXa, a serine protease with structura...
متن کاملProteolytic interactions of factor IXa with human factor VIII and factor VIIIa.
Factor IXa was shown to inactivate both factor VIII and factor VIIIa in a phospholipid-dependent reaction that could be blocked by an antifactor IX antibody. Factor IXa-catalyzed inactivation correlated with proteolytic cleavages within the A1 subunit of factor VIIIa and within the heavy chain (contiguous A1-A2-B domains) of factor VIII. Furthermore, a relatively slow conversion of factor VIII ...

15 صفحه اولActivation of factor X by factors IXa and VIII; a specific assay for factor IXa in the presence of thrombin-activated factor VIII.
We studied the activation of factor X by the intrinsic pathway of blood coagulation using a new assay of factor X activation. When factor X tritiated in its sialic acid residues is activated, activation can be measured by the release of tritiated activation peptide, and the initial rate of activation can be determined under varying conditions. In the presence of phospholipid and calcium ions, f...
متن کاملPhospholipid-binding domain of factor VIII is involved in endothelial cell-mediated activation of factor X by factor IXa.
Apparently quiescent, nonapoptotic endothelial cells mediate the activation of factor X by activated factor IX in the presence of its cofactor, activated factor VIII. In a previous study, we reported that during the activation of factor X, the interaction of the cofactor with the endothelial cell membrane clearly differs from the interaction of the cofactor with artificial lipid membranes. In t...
