Details
Function: Fibrinogen has a double function: yielding monomers that polymerize into fibrin and acting as a cofactor in platelet aggregation.

Post-translational modification: Conversion of fibrinogen to fibrin is triggered by thrombin, which cleaves fibrinopeptides A and B from alpha and beta chains, and thus exposes the N-terminal polymerization sites responsible for the formation of the soft clot.

Similarity: Contains 1 fibrinogen C-terminal domain.

Subcellular location: Secreted.

Subunit structure: Heterohexamer; disulfide linked. Contains 2 sets of 3 non-identical chains (alpha, beta and gamma). The 2 heterotrimers are in head to head conformation with the N-termini in a small central domain (By similarity).

Alternative products: Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=P14480-1; Sequence=Displayed; Name=2; IsoId=P14480-2; Sequence=VSP_022492, VSP_022493; Note=No experimental confirmation available.

Sequence length: 479 AA.
