Fibrinogen γ Monoclonal Antibody

disease:Defects in FGG are a cause of congenital afibrinogenemia [MIM:202400]. It is a rare autosomal recessive disorder characterized by complete absence of detectable fibrinogen.,disease:Defects in FGG are a cause of thrombophilia.,domain:A long coiled coil structure formed by 3 polypeptide chains connects the central nodule to the C-terminal domains (distal nodules). The long C-terminal ends of the alpha chains fold back, contributing a fourth strand to the coiled coil structure.,function:Fibrinogen has a double function: yielding monomers that polymerize into fibrin and acting as a cofactor in platelet aggregation.,miscellaneous:The gamma-chain carries the main binding site for the platelet receptor.,online information:Fibrinogen entry,PTM: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. The soft clot is converted into the hard clot by factor XIIIA which catalyzes the epsilon-(gamma-glutamyl)lysine cross-linking between gamma chains (stronger) and between alpha chains (weaker) of different monomers.,PTM:Sulfation of C-terminal tyrosines increases affinity for thrombin.,similarity:Contains 1 fibrinogen C-terminal domain.,subunit: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.,
