Histaminylation of fibrinogen by tissue transglutaminase-2 (TGM-2): potential role in modulating inflammation.
Lai T.S., Greenberg C.S.
Plasma fibrinogen plays an important role in hemostasis and inflammation. Fibrinogen is converted to fibrin to impede blood loss and serves as the provisional matrix that aids wound healing.

Plasma fibrinogen plays an important role in hemostasis and inflammation. Fibrinogen is converted to fibrin to impede blood loss and serves as the provisional matrix that aids wound healing. Fibrinogen also binds to cytokine activated endothelial cells and promotes the binding and migration of leukocytes into tissues during inflammation. Tissue transglutaminase (TGM-2) released from injured cells could cross-link fibrinogen to form multivalent complexes that could promote adhesion of platelets and vascular cells to endothelium. Histamine released by mast cells is a potent biogenic amine that promotes inflammation. The covalent attachment of histamine to proteins (histaminylation) by TGM-2 could modify local inflammatory reactions. We investigated TGM-2 crosslinking of several biogenic amines (serotonin, histamine, dopamine and noradrenaline) to fibrinogen. We identified histaminylation of fibrinogen by TGM-2 as a preferred reaction in solid and solution phase transglutaminase assays. Histamine caused a concentration-dependent inhibition of fibrinogen cross-linking by TGM-2. Fibrinogen that was not TGM-2 crosslinked bound to unactivated endothelial cells with low affinity. However, the binding was increased by sevenfold when fibrinogen was cross-linked by TGM-2. Histaminylation of fibrinogen also inhibited TGM-2 crosslinking of fibrinogen and the binding to un-activated HUVEC cells by 75–90 %. In summary, the histaminylation of fibrinogen by TGM-2 could play a role in modifying inflammation by sequestering free histamine and by inhibiting TGM-2 crosslinking of fibrinogen. << Less

Transglutaminase-mediated transamidation of serotonin, dopamine and noradrenaline to fibronectin: evidence for a general mechanism of monoaminylation.
Hummerich R., Thumfart J.O., Findeisen P., Bartsch D., Schloss P.
The activity of some small GTPases is regulated by covalent transamidation of serotonin (5-hydropxytryptamien) to glutamine residues of the enzymes.

The activity of some small GTPases is regulated by covalent transamidation of serotonin (5-hydropxytryptamien) to glutamine residues of the enzymes. This process is mediated by transglutaminase (TGase) and is termed "serotonylation". In addition, serotonylation of neural proteins and proteins of the extracellular matrix such as fibronectin has been demonstrated. Here we show that the catecholamines dopamine (DA) and noradrenaline (NA) inhibit serotonylation of fibronectin and that DA and NA themselves can be selectively transamidated into fibronectin by TGase. All three biogenic monoamines also block TGase-mediated transamidation of another monoamine, monodansylacadaverine, into fibronectin, suggesting a general mechanism of TGase-mediated "monoaminylation". << Less
