Factor XIIIa-dependent retention of red blood cells in clots is mediated by fibrin α-chain crosslinking. Blood 2015; 126:1940-8.

Abstract
Factor XIII(a) [FXIII(a)] stabilizes clots and increases resistance to fibrinolysis and mechanical disruption. FXIIIa also mediates red blood cell (RBC) retention in contracting clots and determines venous thrombus size, suggesting FXIII(a) is a potential target for reducing thrombosis. However, the mechanism by which FXIIIa retains RBCs in clots is unknown. We determined the effect of FXIII(a) on human and murine clot weight and composition. Real-time microscopy revealed extensive RBC loss from clots formed in the absence of FXIIIa activity, and RBCs exhibited transient deformation as they exited the clots. Fibrin band-shift assays and flow cytometry did not reveal crosslinking of fibrin or FXIIIa substrates to RBCs, suggesting FXIIIa does not crosslink RBCs directly to the clot. RBCs were retained in clots from mice deficient in α2-antiplasmin, thrombin-activatable fibrinolysis inhibitor, or fibronectin, indicating RBC retention does not depend on these FXIIIa substrates. RBC retention in clots was positively correlated with fibrin network density; however, FXIIIa inhibition reduced RBC retention at all network densities. FXIIIa inhibition reduced RBC retention in clots formed with fibrinogen that lacks γ-chain crosslinking sites, but not in clots that lack α-chain crosslinking sites. Moreover, FXIIIa inhibitor concentrations that primarily block α-, but not γ-, chain crosslinking decreased RBC retention in clots. These data indicate FXIIIa-dependent retention of RBCs in clots is mediated by fibrin α-chain crosslinking. These findings expose a newly recognized, essential role for fibrin crosslinking during whole blood clot formation and consolidation and establish FXIIIa activity as a key determinant of thrombus composition and size.

Abstract
Transglutaminases (TGs) are a family of enzymes that catalyze the formation of covalent gamma-glutamyl-epsilon-lysine crosslinks between glutamine (Q) acyl-donors and lysine (K) acyl-acceptors. Here, we report the cDNA cloning of a TG from mouse reticulocytes, its 4.6-kb message size and high-yield synthesis of recombinant TG in yeast cultures. Its activity was assayed by crosslinking the amine of monodansylcadaverine (DC) onto casein and inside-out vesicles of erythrocytes. The latter contain TG substrates including the anion ion exchanger (AE1) or band 3, and the crosslinking activity was the highest at physiological [GTP] and [ATP] of erythrocytes. To study individually how TG interacts with band 3 and what role P4.2, a pseudo-TG that is normally associated with band 3, may play in their interaction, recombinant cytoplasmic domain of band 3 (cdb3) and P4.2 were also cloned by polymerase chain reaction from mouse reticulocytes, expressed and affinity-purified from Escherichia coli. Enzyme-linked immunosorbent assay and Western blot analysis revealed that increasing [CaCl(2)] enhanced TG-mediated crosslinking of DC to cdb3 but decreased TG binding to cdb3. P4.2 inhibited the TG-mediated crosslinking of cdb3 but stabilized the binding of TG to cdb3 in the presence of calcium. This in vitro study suggests a relationship among TG, cdb3 and P4.2 in erythrocyte membrane during calcium influx.

Abstract
The complete amino acid sequence for human erythrocyte band 4.2 has been derived from the nucleotide sequence of a full-length 2.35-kilobase (kb) cDNA. The 2.35-kb cDNA was isolated from a human reticulocyte cDNA library made in the expression vector lambda gt11. Of the 2348 base pairs (bp), 2073 bp encode 691 amino acids representing 76.9 kDa (the SDS/PAGE molecular mass is 72 kDa). RNA blot analysis of human reticulocyte total RNA gives a message size for band 4.2 of 2.4 kb. The amino acid sequence of band 4.2 has homology with two closely related Ca2(+)-dependent cross-linking proteins, guinea pig liver transglutaminase (protein-glutamine gamma-glutamyltransferase; protein-glutamine: amine gamma-glutamyltransferase, EC 2.3.2.13) (32% identity in a 446-amino acid overlap) and the a subunit of human coagulation factor XIII (27% identity in a 639-amino acid overlap), a transglutaminase that forms intermolecular gamma-glutamyl-epsilon-lysine bonds between fibrin molecules. The region of greatest identity includes a 49-amino acid stretch of band 4.2, which is 69% and 51% identical with guinea pig liver transglutaminase and the a subunit of factor XIII, respectively, within the regions that contain the active sites of these enzymes. Significantly, within the five contiguous consensus residues of the transglutaminase active site, Gly-Gln-Cys-Trp-Val, band 4.2 has an alanine substituted for cysteine (which is apparently essential for activity). Consistent with this active site substitution, erythrocyte membranes or inside-out vesicles, which contain band 4.2, show no evidence of transglutaminase activity by two types of in vitro assay.

Abstract
During an examination of the effects of shear and of the Ca2+ ionophore A23187 on Ca2+ entry into erythrocytes of rats and humans, we noted that rat erythrocytes were much more sensitive to Ca2+-induced hemolysis than the human cells. An examination of the effect of Ca2+ on transglutaminase, a cytosolic enzyme in the erythrocyte which cross-links membrane proteins and renders cells less deformable, demonstrated a correlation between enzyme activity and Ca2+-induced hemolysis. Both rat and human cells subjected to shear-induced Ca2+ entry exhibited increased enzyme activity and altered membrane protein SDS-PAGE patterns. Twenty micromolar A23187 with Ca2+ at concentrations above 80 microM caused hemolysis of rat erythrocytes. In contrast to human erythrocytes, under these conditions no membranes were recoverable from rat erythrocytes. At lower concentrations of Ca2+ (25 and 50 microM), however, rat erythrocytes maintained integrity, and exhibited enhanced transglutaminase activity and cross-linking of membrane proteins. The rat enzyme can be activated 30% by 10 microM Ca2+, while 50 microM Ca2+ was necessary to achieve a similar activation of the enzyme from human red blood cells. In studies of shear-stimulated Ca2+ uptake by erythrocytes the rat red cell enzyme was more readily activated. The SDS-PAGE pattern of rat red cell membranes after a 30 sec shear showed specific changes in protein banding, including the appearance of bands greater than 330 kDa. Changes in protein banding were also apparent in cytosolic proteins. This work supports the view that shear-induced Ca2+ entry activates transglutaminase that leads to cross-linking of membrane components, a loss of cell integrity, and eventual cell death.

Abstract
The effects of copper on the activity of erythrocyte (Ca2+ + Mg2+)-ATPase have been tested on membranes stripped of endogenous calmodulin or recombined with purified calmodulin. The interactions of copper with Ca2+, calmodulin and (Mg-ATP)2- were determined by kinetic studies. The most striking result is the potent competitive inhibition exerted by (Cu-ATP)2- against (Mg-ATP)2- (Ki = 2.8 microM), while free copper gives no characteristic inhibition. Our results also demonstrate that copper does not compete with calcium either on the enzyme or on calmodulin. The fixation of calmodulin on the enzyme is not altered in the presence of copper as shown by the fact that the dissociation constant remains unaffected. It may be speculated that (Cu-ATP)2- is the active form of copper, which could plausibly be at the origin of some of the pathological features of erythrocytes observed in conditions associated with excess copper.

Abstract
Polyamines are mainly transported in the blood by erythrocytes: Putrescine, spermidine and spermine can be taken up in vitro by red blood cells (RBC); their entry is greater in the presence of serum than in the presence of plasma, and spermine entry is lower than that observed for the two other polyamines. In the presence of serum, the affinity of RBC for spermidine is 30 fold greater than that for putrescine. The majority of RBC polyamines are present in the hemolysate and are not complexed to high molecular weight material. At + 4 degrees C the polyamine uptake is considerably reduced and for putrescine and spermine practically non existent, but it seems that it is internalization rather than binding which constitutes the dependent step. Though intracellular spermidine and spermine levels reflect differences in uptake rather than in outward flux across the cell membrane, the values of putrescine appear to be the resultant of influx and efflux. The presence of specific receptor sites for polyamines visualized by SEM on the surface of RBC using latex-putrescine spheres, confirms the results obtained with labelled polyamines. Therefore, only the understanding of the polyamine repartition inside the blood compartments would permit the clinical use of those molecules as non statistical tumor markers.

Abstract
The effects of the transglutaminase inhibitor dansyl cadaverine (DC) and the polyamine antagonist methyl glyoxal-bis-(guanylhydrazone) (MeGbG) on the response of lymphocytes towards allogeneic and lectin stimulation and on the zymosan-induced chemiluminescence of neutrophilic granulocytes was studied. Application of DC resulted in dose-dependent suppression of chemiluminescence and lymphocyte proliferation; no difference of inhibitory potential occurred with variation of incubation time in the latter system. MeGbG was inactive in granulocytes, but inhibited lymphocyte proliferation; its effect increased with time. The experiments provide further evidence for the importance of transglutaminases and polyamines for the function of immunocompetent cells.

Abstract
Guinea pig liver transglutaminase has been used to incorporate putrescine into horse heart cytochrome c. The native protein showed essentially no incorporation, while ethanol-denatured cytochrome c incorporated almost 1 mol putrescine per mol protein. No increase in this level of modification was obtained when maleylated cytochrome c and the tryptic peptides of cytochrome c were used as substrates. Analysis of the modified ethanol-denatured cytochrome c by tryptic cleavage and peptide isolation showed that glutamine-42 of the intact protein is the site of incorporation of radioactively labelled putrescine. Ethanol-denatured cytochrome c that was specifically modified at glutamine-42 by incorporated of putrescine could be readily renatured. The renatured modified protein showed reactivity with cytochrome c oxidase comparable to that of the original native protein.

Abstract
The effects of Ca2+ on human erythrocyte membrane proteins were examined by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis. Ca2+ had several effects on normal human erythrocyte membrane proteins. It affected the binding of cytoplasmic proteins to the membrane, produced a non-reversible aggregation of several membrane proteins and activated apparent proteolysis of membrane proteins. The Ca2+ effect could be obtained with isolated, washed membranes when the erythrocyte cytoplasm was added. These studies indicate that the Ca2+-induced membrane proteolysis and aggregation effects are not due simply to its presence at the time of hemolysis as previously suggested (Carraway, K.L., Triplett, R.B. and Anderson, D.R. (1975) Biochim. Biophys. Acta 379, 571-581), but are the result of more complex interactions between the erythrocyte membrane and cytoplasmic factors.

Abstract
Incubation of cultured human fibroblasts with blood coagulation factor XIIIa (plasma transglutaminase, fibrinoligase) and the fluorescent primary amine, N-(5-aminopentyl)-5-dimethylaminonaphthalene-1-sulfonamide, resulted in fluorescent labeling of three cellular polypeptides. The molecular weights of the labeled polypeptides, estimated by polyacrylamide gel electrophoresis in sodium dodecyl sulfate after reduction, were: greater than 1.2-10(6), 2.2-10(5), and 1.3-10(5). The labeled 2.2-10(5) dalton polypeptide was susceptible to mild trypsinization and not present in cultures of SV-40 transformed fibroblasts, indicating that it is the subunit of cell-surface fibronectin and identical with the external transformation-sensitive polypeptide of similar molecular weight described by others. Upon coelectrophoresis, the labeled 2.2-10(5) dalton polypeptide migrated slightly behind the subunit of plasma fibronectin (cold-insoluble globulin), indicating that the immunologically cross-reactive forms of fibronectin in human plasma and cultured human fibroblasts differ slightly in molecular weight. The identities of the labeled greater than 1.2-10(6) and 1.3-10(5) dalton polypeptides are not known. The XIIa-reactive glutamine residues of fibroblast cell-surface proteins are potential sites for intermolecular cross-linking (by xi-(gamma-glutamyl)lysyl linkages) to other proteins of connective tissue.

Abstract
The surface proteins of cultured human skin fibroblasts were iodinated and then exposed to one or more of the following blood coagulation proteins: thrombin, fibrinogen, and factor XIII (plasma protransglutaminase). Radiolabeled polypeptides were analyzed by polyacrylamide gel electrophoresis in the presence of sodium dodecylsulfate. After exposure to physiological concentrations of activated factor XIII (XIIIa), the band of radioactivity corresponding to the major labeled surface protein (fibronectin, molecular weight = 2.2 x 10(5) daltons) was cross-linked to a very high molecular weight complex. The cross-linking reaction was inhibited by fibrin (which is known to bind the catalytic subunit of XIIIa). Cross-linking of labeled cell surface fibronectin to fibrin could not be demonstrated. The fibrillar pattern of surface fibronectin appeared unaffected by cross-linking when studied by immunofluorescence. Cross-linking of cell surface fibronectin by XIIIa requires highly specific enzyme-substrate and protein-protein interactions, and may be an important physiological reaction.
