Description
Product Characteristics:
Factor VIII, along with calcium and phospholipid, acts as a cofactor for factor IXa when it converts factor X to the activated form, factor Xa.
Subcellular location: Secreted, Extracellular matrix
Synonyms: AHF, F8B, F8C, HEMA, FVIII, DXS1253E, Coagulation factor VIII, Antihemophilic factor, Procoagulant component, F8
Target Information: 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. Transcript variant 1 encodes a large glycoprotein, isoform a, which circulates in plasma and associates with von Willebrand factor in a noncovalent complex. This protein undergoes multiple cleavage events. Transcript variant 2 encodes a putative small protein, isoform b, which consists primarily of the phospholipid binding domain of factor VIIIc. This binding domain is essential for coagulant activity. Defects in this gene results in hemophilia A, a common recessive X-linked coagulation disorder. [provided by RefSeq, Jul 2008]
