F8A : Factor VIII is synthesized in the liver and, perhaps, in other tissues. It is a coagulation cofactor that circulates bound to von Willebrand factor and is part of the intrinsic coagulation pathway. The biological half-life is 9 to 18 hours (average is 12 hours).

Summary: This gene encodes coagulation factor VIII, which participates in the intrinsic pathway of blood coagulation; factor VIII is a cofactor for factor IXa which, in the presence of Ca+2 and phospholipids, converts factor X to the activated form Xa. This gene produces two alternatively spliced transcripts.

Coagulation factors XII, XI, and VIII (FXII, FXI, and FVIII) have been implicated in first thrombotic events, and our aim was to estimate their effects on vascular outcomes within 3 years after first stroke. Human coagulation factor VIII circulates in plasma mainly as a two-chain glycosylated protein with 1 heavy (relative molecular mass of about 200 000) and 1 light (relative molecular mass 80 000) chain held together by divalent metal ions. Human coagulation factor VIII (rDNA) is prepared as full-length factor VIII (octocog alfa), or as a Factor VIII can be converted into its active form by proteolysis in both the heavy and light chain by various serine proteases (closed downward arrows), including thrombin and factor Xa. Because proteolysis by factor Xa but not thrombin is inhibited by vWF, thrombin is probably the physiological activator of factor VIII. The F8 gene encodes coagulation factor VIII, a large plasma glycoprotein that functions in the blood coagulation cascade as a cofactor for the factor IXa -dependent activation of factor X (F10; 613872). Factor VIII is activated proteolytically by a variety of coagulation enzymes, including thrombin (F2; 176930). Coagulation factor VIII Synonyms.

To increase expression, we used codon-optimization of a B-domain deleted FVIII (BDD-FVIII). This resulted in 7-fold increase of the expression level in cell culture. coagulation factors factors essential to normal blood clotting, whose absence, diminution, or excess may lead to abnormality of the clotting.Twelve factors, commonly designated by Roman numerals, have been described (I–V and VII–XIII; VI is no longer considered to have a clotting function). One study showed that both symptoms are caused by a malfunction of the immune system due to a deficiency of factor VIII, as well as characterising the ways in which this happens. In healthy subjects, the formation of a wound immediately activates the coagulation cascade, which also involves factor VIII. Factor VIII can be converted into its active form by proteolysis in both the heavy and light chain by various serine proteases (closed downward arrows), including thrombin and factor Xa. Because proteolysis by factor Xa but not thrombin is inhibited by vWF, thrombin is probably the physiological activator of factor VIII.

In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Coagulation factor VIII activity. Coagulation factor VIII activity, per vial or millilitre of reconstituted solution, should be specified in the Normative Document.

Coagulation factor VIII is made chiefly by cells in the liver. This protein circulates in the bloodstream in an inactive form, bound to another molecule called von Willebrand factor, until an injury that damages blood vessels occurs. In response to injury, coagulation factor VIII is activated and separates from von Willebrand factor.
