Factor V

Mammalian protein found in humans

Coagulation factor V, also less commonly known as proaccelerin or labile factor, is a protein involved in coagulation, encoded, in humans, by F5 gene. In contrast to most other coagulation factors, it is not enzymatically active but functions as a cofactor. Factor V deficiency leads to predisposition for hemorrhage, while some mutations predispose for thrombosis.
