[alphaC domains of fibrinogen molecules as the structures accelerating fibrin assembly].
Preparation of monomeric fibrin lacking intact alpha C-domains (monomeric X1-fragment), but fully clottable, is described. The assembly process of both monomeric fibrin and monomeric X1-fragment has been studied by electron microscopy and light scattering methods. It was shown that both proteins form similar fibrils with characteristic cross-banding. Upon dilution a sharp elevation of the differences between the assembly rates of monomeric X1-fragment and monomeric fibrin was revealed. The results obtained show that alpha C-domains take part in fibrin clot formation not as structural components but as the factor accelerating the ordered assembly of complex fibrin structure. The possible mechanism of alpha C-domains participation in fibrin clot formation are regarded.
