== Publication Abstract from PubMed ==
The human fibrinogen gamma-chain C-terminal segment functions as the platelet integrin binding site as well as the Factor XIIIa cross-linking substrate and thus plays an important role in blood clot formation and stabilization. The three-dimensional structure of this segment has been determined using carrier protein driven crystallization. The C-terminal segment, gamma-(398-411), was attached to a linker sequence at the C-terminus of glutathione S-transferase and the structure of this fusion protein determined at 1.8 A resolution. Functional studies of the chimeric protein demonstrate that the fibrinogen sequence in the presence of the carrier protein retains its specific functions as ligand for platelet integrin alpha(IIb)beta3 (gpIIb/IIIa) and as a cross-linking substrate for Factor XIIIa. The structure obtained for the fibrinogen gamma-chain segment is not affected by crystal packing and can provide the missing links to the recently reported model of cross-linked fibrin.

Disease

FIBG_HUMAN Defects in FGG are a cause of congenital afibrinogenemia (CAFBN) [MIM:202400. This rare autosomal recessive disorder is characterized by bleeding that varies from mild to severe and by complete absence or extremely low levels of plasma and platelet fibrinogen. Note=Patients with congenital fibrinogen abnormalities can manifest different clinical pictures. Some cases are clinically silent, some show a tendency toward bleeding and some show a predisposition for thrombosis with or without bleeding.

Function

GST26_SCHJA Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. GST isoenzymes appear to play a central role in the parasite detoxification system. Other functions are also suspected including a role in increasing the solubility of haematin in the parasite gut.FIBG_HUMAN Fibrinogen has a double function: yielding monomers that polymerize into fibrin and acting as a cofactor in platelet aggregation.
