XIIIs bind to the clot via their B units. Abstract Over the last two decades, it became evident that factor XIII (FXIII) is not only a crucial determinant of clot characteristics but also has potentially important functions in many various fields such as bone biology, immunity, and adipogenesis. A. Factor XIII A Subunit and Cellular Factor XIII FXIII-A, a protransglutaminase, belongs to the family of TGs. Eight members of the family (FXIII-A and TG1-TG7) possess potential enzymatic activity; while an additional protein, erythrocyte band 4.2, has a similar domain struc-ture but, due to the replacement of active site amino acid, Factor XIII (FXIII) is an unusual blood coagulation factor, circulating as a heterotetramer composed of two catalytic A-subunits and two noncatalytic B-subunits. It is a plasma transglutaminase (TG), mostly associated with fibrinogen, which is activated by thrombin in the presence of calcium in the final stages of the coagulation cascade. Factor XIII (FXIII) is unique among clotting factors for a number of reasons: 1) it is a protransglutaminase, which becomes activated in the last stage of coagulation; 2) it works on an insoluble s Factor XIII is the last step of the clotting cascade, and it functions to stabilize the clot. Mutations of the F13A1 or the F13b gene result in deficient levels of functional factor XIII, which causes blood clots to be weak and unstable resulting in fast breakdown. Factor XIII deficiency is an extremely rare inherited blood disorder characterized by abnormal blood clotting that may result in abnormal bleeding.

2010 — The effective neutron multiplication factor must not exceed 0.95 in the Figure 13 – keff as function of enrichment for a disposal canister with and products to reduce the burden on the environment play a vital role in this work. vPvB substances in accordance with Annex XIII of the REACH Regulation missing, an assessment factor should be used, as described in Appendix 2:. Function Within blood, thrombins cleave fibrinogens to fibrins during coagulation and a fibrin-based blood clot forms. Factor XIII is a transglutaminase that circulates in the human blood as a heterotetramer of two A and two B subunits.

Factor XIII deficiency occurs exceedingly rarely, causing a severe bleeding tendency. The incidence is one in a million to one in five million people, with higher incidence in areas with consanguineous marriage such as Iran that has the highest global incidence of the disorder. 2007-04-17 · Factor XIII subunit B deficiency (FA13BD) 4 Publications The disease is caused by variants affecting the gene represented in this entry. Disease description An autosomal recessive hematologic disorder characterized by a life-long bleeding tendency, impaired wound healing and spontaneous abortion in affected women.

Mounting evidence now suggests that platelet FXIII-A Plasma factor XIII (pFXIII) is the last enzyme in the blood coagulation cascade and in contrast to all other enzymes involved, it is not a serine protease but a transglutaminase, catalyzing the formation of isopeptide bonds between the side chains of glutamine and lysine residues.
