| Human Factor XIII | Factor XIII is the zymogenic form of the glutaminyl-peptide g-glutamyl transferase factor XIIIa (fibrinoligase, plasma transglutaminase, fibrin stabilizing factor, E.C. 2.3.2.13). Factor XIII is unique among transamidases in that it is a zymogen in vivo. Factor XIII is found both extracellularly in plasma and intracellularly in platelets, megakaryocytes, monocytes, placenta, uterus, liver and prostrate tissues. Plasma factor XIII is synthesized in the liver and circulates as a tetramer (Mr=320,000), composed of 2 pairs of nonidentical subunits (A2B2). The intra-cellular forms are synthesized in the tissues where they reside as dimers (Mr=146,000) of 2 identical A chains (A2). The A ...nly after the Ca2+ (Kd=10-3M) and fibrin(ogen) (Kd=10-8M) dependent dissociation of the B subunit dimer from the A2' dimer.In the coagulation cascade, factor XIIIa functions to stabilize the fibrin clot by crosslinking the a and g-chains of fibrin. Other proteins known to be substrates for Factor XIIIa which may be hemostatically important include fibronectin, α2-antiplasmin, collagen, factor V, von Willebrand Factor and thrombospondin.Factor XIII is purified from fresh frozen human plasma by a modification of the procedures described by Folke and Lorand involving barium citrate, ammonium sulfate and glycine precipitations, ion exchange chromatography and gel filtration.
