Tissue transglutaminase (tTG) catalyzes a Ca(2+)-dependent transglutaminase (TGase) activity that stabilizes tissues and a GTP hydrolysis activity that regulates cell receptor signaling. The purpose of this study was to examine the true substrates fo

Human factor XIII (FXIII) and tissue transglutaminase (tTG) are homologous proteins. FXIII requires thrombin for activation and cross-links the gamma chains of fibrin(ogen) more efficiently than the Aalpha chains. On the other hand, tTG is thrombin-i

Factor XIIIa (FXIIIa) stabilizes fibrin clots by covalently cross-linking fibrin molecules. The purpose of this study was to determine the amino acid requirements at the active site of FXIIIa for catalysis. We selected amino acids 310-317 (Arg-Tyr-Gl

The carboxy-terminus of the gamma chain of fibrinogen contains a sequence which is believed to be one of the domains that interacts with glycoprotein (GP) IIb/IIIa to support platelet aggregation. A normal variant of fibrinogen exists in which the fo

Tissue transglutaminase (TG) is an enzyme that stabilizes the structure of tissues by covalently ligating extracellular matrix molecules. Expression and localization of TG are not well established during wound healing. We performed punch biopsy wound

In the present study, we investigated the role of cAMP-dependent protein kinase in the process of Ca2+ uptake and release from platelet-derived membrane vesicles enriched in the dense tubular system. It was found that these membrane vesicles contain
