" /> factor xiia - CISMeF





Preferred Label : factor xiia;

MeSH definition : Activated form of factor XII. In the initial event in the intrinsic pathway of blood coagulation, kallikrein (with cofactor HIGH MOLECULAR WEIGHT KININOGEN) cleaves factor XII to XIIa. Factor XIIa is then further cleaved by kallikrein, plasmin, and trypsin to yield smaller factor XII fragments (Hageman-Factor fragments). These fragments increase the activity of prekallikrein to kallikrein but decrease the procoagulant activity of factor XII.;

MeSH synonym : activator, prekallikrein; coagulation factor xiia; activated factor xii; factor xii, activated; factor xiia, coagulation; prekallikrein activator; blood coagulation factor xii, activated; Factor Twelve A; Factor 12A;

CISMeF synonym : xiia, coagulation factor;

MeSH hyponym : Hageman-Factor fragments; Fragments, Hageman-Factor; Hageman Factor Fragments;
