Recombinant Human Fibrinogen beta chain (FGB), Truncated

Uniprot Id

P02675

Target Species

Human

Target Name

FGB

Target Full Name

Fibrinogen beta chain

Target Function

Cleaved by the protease thrombin to yield monomers which, together with fibrinogen alpha (FGA) 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. In addition, functions during the early stages of wound repair to stabilize the lesion and guide cell migration during re-epithelialization. Was originally thought to be essential for platelet aggregation, based on in vitro studies using anticoagulated blood. However subsequent studies have shown that it is not absolutely required for thrombus formation in vivo. Enhances expression of SELP in activated platelets. Maternal fibrinogen is essential for successful pregnancy. Fibrin deposition is also associated with infection, where it protects against IFNG-mediated hemorrhage. May also facilitate the antibacterial immune response via both innate and T-cell mediated pathways.

Target Involvement

Congenital afibrinogenemia (CAFBN); Dysfibrinogenemia, congenital (DYSFIBRIN)

Target Subcellular Location

Secreted.

Target Tissue Specificity

Detected in blood plasma (at protein level).

Target Synonyms

Beta fibrinogen; Epididymis Secretory Sperm Binding Protein Li 78p; FGB; FIBB_HUMAN; Fibrinogen beta chain; Fibrinogen; B Beta Polypeptide; HEL-S-78p

Target Background

The protein encoded by this gene is the beta component of fibrinogen, a blood-borne glycoprotein comprised of three pairs of nonidentical polypeptide chains. Following vascular injury, fibrinogen is cleaved by thrombin to form fibrin which is the most abundant component of blood clots. In addition, various cleavage products of fibrinogen and fibrin regulate cell adhesion and spreading, display vasoconstrictor and chemotactic activities, and are mitogens for several cell types. Fibrinogen serves key roles in hemostasis and antimicrobial host defense. Mutations in this gene lead to several disorders, including afibrinogenemia, dysfibrinogenemia, hypodysfibrinogenemia and thrombotic tendency.
