Structure and function of factor XI.
Factor XI (FXI) is the zymogen of an enzyme (FXIa) that contributes to hemostasis by activating factor IX. Although bleeding associated with FXI deficiency is relatively mild, there has been resurgence of interest in FXI because of studies indicating it makes contributions to thrombosis and other processes associated with dysregulated coagulation. FXI is an unusual dimeric protease, with struct...
متن کاملCharacterization 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 کاملHuman blood coagulation factor XI. Purification, properties, and mechanism of activation by activated factor XII.
Human blood coagulation Factor XI was purified in 20% yield from plasma by ion exchange chromatography. The specific clotting activity of purified Factor XI was 250 & 20 units/mg implying that its concentration in normal titrated human plasma is 4 pg/ml. The purified Factor XI in its precursor form gave a single protein band on polyacrylamide gels in the presence of sodium dodecyl sulfate with ...
متن کاملExpression of Human Blood Coagulation Factor XI: Characterization of the Defect in Factor XI Type I11 Deficiency
Human factor XI (FXI) is a blood coagulation factor participating in the early phase of the intrinsic pathway of blood coagulation. It circulates in blood as a glycoprotein composed of two identical chains held together by a single disulfide bond between the fourth apple domains. FXI has been expressed in baby hamster kidney (BHK) cells, where it was synthesized as a single-chain molecule that ...
