Characterization of the Human Blood Coagulation Factor XI 1 Gene
A human genomic phage library was screened using a human factor XI1 cDNA as a hybridization probe. Two overlapping phage clones were isolated which contain the entire human factor XI1 gene. DNA sequence and restriction enzyme analysis of the clones indicate that the gene is approximately 12 kilobase pairs in size and is comprised of 13 introns and 14 exons. Exons 3-14 are contained in a genomic...
متن کاملBlood Coagulation
INTRODUCTION This section covers the means, as far as we now know them, by which components of the blood plasma produce an insoluble protein meshwork, or gel, at a site of blood-vessel damage. The plasma is normally completely fluid, containing all its proteins in soluble form. When the clotting system is activated at a site of blood-vessel damage, a series of proteolytic reactions is set going...
متن کاملTissue factor-dependent autoactivation of human blood coagulation factor VII.
We recently showed that single-chain zymogen factor VII is converted to two-chain factor VIIa in an autocatalytic manner following complex formation with either cell-surface or solution-phase relipidated tissue factor apoprotein (Nakagaki, T., Foster, D. C., Berkner, K. L., and Kisiel, W. (1991) Biochemistry 30, 10819-10824). We have now performed a detailed kinetic analysis of the autoactivati...
متن کاملAn alternative extrinsic pathway of human blood coagulation.
To study the interrelationships of the major human coagulation pathways, factor X activation in normal and various deficient human plasmas was evaluated when clotting was triggered by dilute rabbit or human thromboplastin. Various dilutions of thromboplastin were added to plasma samples containing 3H-labeled factor X, and the time course of factor X activation was determined. At a 1/250 dilutio...
متن کاملDisorders of the blood coagulation-fibrinolytic system
Most human cells have no direct contact with the external environment and their living conditions are ensured by blood. An essential criterion for normal blood circulation is the ability of the blood to arrest bleeding at sites of tissue injury and to prevent thrombus formation inside the blood vessels under normal conditions. The balance between these two extreme states is rigorously controlle...
