Coagulation factor XIII (FXIII) is a plasma-circulating heterotetrameric pro-transglutaminase complex that is composed of two catalytic FXIII-A and two protective/regulatory FXIII-B subunits. FXIII acts by forming covalent cross-links within a preformed fibrin clots to prevent its premature fibrinolysis. The FXIII-A subunit is known to have pleiotropic roles outside coagulation, but the FXIII-B subunit is a relatively unexplored entity, both structurally as well as functionally. Its discovered roles so far are limited to that of the carrier/regulatory protein of its partner FXIII-A subunit. In the present study, we have explored the co-presence of protein excipients in commercial FXIII plasma concentrate FibrogamminP by combination of protein purification and mass spectrometry-based verification. Complement factor H was one of the co-excipients observed in this analysis. This was followed by performing pull down assays from plasma in order to detect the putative novel interacting partners for the FXIII-B subunit. Complement system proteins, like complement C3 and complement C1q, were amongst the proteins that were pulled down. The only protein that was observed in both experimental set ups was alpha-2-macroglobulin, which might therefore be a putative interacting partner of the FXIII/FXIII-B subunit. Future functional investigations will be needed to understand the physiological significance of this association.

There is a wide normal range of coagulation factor XIII activity that has never been adequately explained. A polymorphism substituting leucine for valine at position 34 in the activation peptide of the A subunit of factor XIII has recently been discovered in nondeficient individuals, and the present studies indicate that the leucine substitution results in a significant increase in transglutaminase activity. The frequency of the Leu34 allele in the Australian Caucasian population is 0.27, which is high enough to suggest that the inheritance of either the Val34 or Leu34 alleles may contribute to the wide normal range of activity. Although there has been structural evidence indicating that the activation peptide does not dissociate from the enzyme after thrombin cleavage, the discovery of elevated activity resulting from the Leu34 substitution is the first direct evidence that the activation peptide plays a continuing role in the function of factor XIII. © 1998 by The American Society of Hematology.
