Details
Function: 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.

Post-translational modification: Sulfation on Tyr-1699 is essential for binding vWF.

Similarity: Belongs to the multicopper oxidase family. Contains 3 F5/8 type A domains. Contains 2 F5/8 type C domains. Contains 6 plastocyanin-like domains.

Subcellular location: Secreted, extracellular space.

Subunit structure: Interacts with vWF. vWF binding is essential for the stabilization of F8 in circulation.

Disease: Defects in F8 are the cause of hemophilia A (HEMA)

Sequence length: 2351 AA.
