Gene Gene information from NCBI Gene database.
Entrez ID 2243
Gene name Fibrinogen alpha chain
Gene symbol FGA
Synonyms (NCBI Gene)
AMYLD2Fib2
Chromosome 4
Chromosome location 4q31.3
Summary This gene encodes the alpha subunit of the coagulation factor fibrinogen, which is a component of the blood clot. Following vascular injury, the encoded preproprotein is proteolytically processed by thrombin during the conversion of fibrinogen to fibrin.

Protein name Fibrinogen alpha chain [Cleaved into: Fibrinopeptide A; Fibrinogen alpha chain]
Protein function 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 o
