Details
Function: Coagulation factor V is a cofactor that participates with factor Xa to activate prothrombin to thrombin.

Post-translational modification: Thrombin activates factor V proteolytically to the active cofactor, factor Va (formation of a heavy chain at the N-terminus and a light chain at the C-terminus).

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 (By similarity).

Subunit structure: Factor Va is composed of a heavy chain and a light chain, noncovalently bound. The interaction between the two chains is calcium-dependent.

Sequence length: 1459 AA.
