WebSUMMARY. The coagulation cascade consists of a complex network of reactions that are essential for the conversion of zymogens into enzymes and of inactive procofactors into cofactors. Most of these reactions take place on a membrane surface, which restricts coagulation to the site of injury. WebPar double-hybride en levure, j'ai montré que deux sérine-protéases, le facteur C et la protéine C2/Bf, impliquées respectivement dans la coagulation sanguine et l'activation du complément, interagissent avec GBP, CL-5 et CRP. Ces sérine-protéases sont organisées en domaines bien définis.
