UniProtKB - P14448 (FIBA_CHICK)
Fibrinogen alpha chain
FGA
Functioni
Cleaved by the protease thrombin to yield monomers which, together with fibrinogen beta (FGB) and fibrinogen gamma (FGG), polymerize to form an insoluble fibrin matrix. Fibrin has a major function in hemostasis as one of the primary components of blood clots.
