Description

Background

Coagulation factor VIII (FVIII) is an essential blood clotting factor also known as anti-hemophilic factor (AHF). In humans, FVIII is encoded by the F8 gene(1-2). Defects in this gene results in hemophilia A, a well known recessive X-linked coagulation disorder(3). Factor VIII participates in blood coagulation; it is a cofactor for factor IXa which, in the presence of Ca+2 and phospholipids forms a complex that converts factor X to the activated form Xa. FVIII is processed from a single-chain polypeptide having the domain structure A 1 -A2-B-A3-C 1 -C2. The heavy chain is composed of domains Al-A2-B while the light chain is composed of domains A3-Cl-C2. The B domain is extensively glycosylated on asparagine, serine, and threonine residues(4). Initial studies showed that deletion of the B domain resulted in a functional molecule as tested by in vitro assays and was expressed more efficiently compared with wildtype FVIII(5).
