**Background of FGG Recombinant Protein**
Fibrinogen gamma chain (FGG) is a critical component of fibrinogen, a large glycoprotein complex essential for blood clotting. Native fibrinogen consists of three pairs of polypeptide chains (Aα, Bβ, and γ), synthesized primarily in hepatocytes. During coagulation, thrombin cleaves fibrinogen to form fibrin monomers, which polymerize into clots. The γ-chain, encoded by the *FGG* gene, plays a pivotal role in clot stability, platelet aggregation, and wound healing.
Recombinant FGG protein is engineered using genetic engineering techniques, often expressed in heterologous systems like *E. coli*, yeast, or mammalian cells (e.g., HEK293 or CHO cells). This approach allows large-scale production of purified FGG with consistent quality, circumventing risks associated with plasma-derived fibrinogen, such as pathogen contamination or batch variability. Recombinant FGG retains functional domains, including binding sites for thrombin, fibrin(ogen) receptors, and crosslinking regions critical for clot formation.
Research on recombinant FGG focuses on understanding fibrinogen’s role in hemostasis, thrombosis, and inflammation. It is also used to develop fibrin-based biomaterials for wound healing, surgical adhesives, or drug delivery systems. Additionally, recombinant FGG aids in studying fibrinogen-related disorders, such as dysfibrinogenemia or hypofibrinogenemia, and in screening therapeutics targeting clot formation or dissolution.
The production of recombinant FGG enables customization, such as introducing mutations to study structure-function relationships or engineering isoforms with enhanced stability or reduced immunogenicity. These advancements highlight its potential in translational medicine and biopharmaceutical applications.
