Coagulation factor XIII is the last zymogen to become activated in the blood coagulation cascade. Plasma factor XIII is a heterotetramer composed of 2 A subunits and 2 B subunits. The A subunits have catalytic function, and the B subunits do not have enzymatic activity and may serve as plasma carrier molecules. Platelet factor XIII is Abstract. Coagulation factor XIII (FXIII) is converted by thrombin into its active form, FXIIIa, which crosslinks fibrin fibers, rendering clots more stable and resistant to degradation. FXIII affects fibrin clot structure and function leading to a more prothrombotic phenotype with denser networks, characterizing patients at risk of venous Factor XIII (FXIII) is an enzyme of the coagulation cascade which plays a key role in maintaining the functional integrity of fibrin clots [].Additionally, FXIII has a range of other functions, including wound healing and tissue repair (Fig. 1).FXIII circulates in plasma as a protransglutaminase comprising two catalytic A and two carrier B subunits INTRODUCTION. Factor XIII (FXIII) is a plasma protein that plays an important role in the final stages of the clotting cascade and the regulation of fibrinolysis. 1, 2 FXIII deficiency, caused by dyspoiesis or increased consumption, results in bleeding tendencies and wound healing complications. 3 Postoperative hemorrhage in patients

Introduction. Fibrinogen comprises duplicate sets of three polypeptide chains; Aα, Bβ and γ [HOST] the final step of blood coagulation, thrombin cleaves fibrinopeptides A and B from fibrinogen, initiating polymerization of fibrin monomers into fibers [HOST] (F) XIII comprises two enzymatic A-subunits and two carrier B-subunits Coagulation factor XIII (FXIII) is a transglutaminase with a well defined role in the final stages of blood coagulation. Active FXIII (FXIIIa) catalyzes the formation of ϵ- (γ-glutamyl)lysine isopeptide bonds between specific Gln and Lys residues. The primary physiological outcome of this catalytic activity is stabilization of the fibrin clot The activity of blood coagulation factor XIII (FXIIIa) plays an important role in rodents as a healing factor after MI, whereas its role in healing and remodelling processes in humans remains unclear. We prospectively evaluated the relevance of FXIIIa after acute MI as a potential early prognostic marker for adequate healing Factor de coagulación XIII. El factor de coagulación XIII, factor XIII, factor estabilizador de la fibrina o factor de Laki-Lorand es una proteína plasmática de síntesis hepática y plaquetaria, que participa en la ruta final común de la hemostasia, estabilizando el coágulo blando de fibrina o polímero de fibrina Coagulation factor XIII (FXIII) is a stepchild among clotting factors. As opposed to all other zymogenic clotting factors, it is not the precursor of a proteolytic enzyme but of a

Factor XIII Deficiency is an ultra-rare bleeding disorder. Bleeding disorders are a group of medical conditions that share an inability or decreased ability to form a stable blood clot. When the body is injured and an area bleeds, a clot is formed to stop the bleeding. Clot formation is a multistep process and is called coagulation. When the blood FXIII-A > % proved to be an independent risk factor for disease progression in NSCLC patients (OR=, 95% CI: , p = ), predicting poor efficacy. The marked decrease in plasma FXIII-A (FXIII-A coagulation disorders and poor prognosis with a short survival time (median survival Objective: To relate factor XIII levels and other prothrombotic markers to inflammatory bowel disease and investigate the frequency of valine34leucine and its effect on factor XIII cross-linking activity in patients with inflammatory bowel disease. Design: Fifty patients with active inflammatory bowel disease but no venous thromboembolism (32 with ulcerative Coagulation factor XIII (FXIII) belongs to the enzyme family of transglutaminases that catalyze the formation of covalent ε-(γ-glutamyl)lysine (amide) bonds on cross-linked Introduction. Congenital factor XIII (FXIII) deficiency is chiefly caused by mutations in the F13A gene (95% of cases) and, more rarely, by F13B gene defects (5% of cases). The F13A gene, coding for the FXIII A protein subunit, occupies chromosomal position 6p24–25 and comprises 15 exons encoding a amino acid protein. 1 Date: 06 August The objective of this document is to guide diagnosis and management of patients with rare coagulation disorders in the UK. The disorders Factor XIII, also known by the name fibrin stabilizing factor, is a key clotting factor in the coagulation cascade known for stabilizing the formation of a blood clot. The plasma form of Factor XIII is a protein heterodimer of A and B subunits expressed by bone marrow and mesenchymal lineage cells remarkable for its function as a Factor XIII deficiency is a type of clotting disorder. A specific protein is missing from the blood so that injured blood vessels cannot heal in the usual way. This information sheet
