Abstract:
:Fibrinogen has been reported to interact with phospholipid; however, the properties of this binding interaction have not been characterized. Purified preparations of human fibrinogen bound to small unilamellar vesicles containing phosphatidylserine (PS) as measured by light scattering and radioisotope filtration. Binding to 100% PS was saturable (apparent Kd=5 microM, Bmax=1.9 g protein/g lipid), reversible, and involved a minor subfraction of the fibrinogen preparation (3-6% of total protein). Fibrinogen interacted minimally with phosphatidylinositol, and not at all with pure phosphatidylcholine (PC) or PC vesicles containing 5% glycosphingolipid (lactosylceramide, ganglioside GM3, ganglioside GD3). Binding efficiency decreased as the PS content of vesicles was diluted with PC. Calcium chloride (2 mM) enhanced protein binding to PS, which was reversed by EDTA. Fibrin clot formation almost quantitatively precipitated the PS binding activity. PS, but not PC, increased the final turbidity of fibrin clots. Computerized sequence analysis of fibrinogen revealed three candidate acidic phospholipid binding motifs located at position 143-210 in the alpha chain, and positions 59-77 and 101-139 in the beta chain. Further study of the PS binding activity of fibrinogen may lead to new insights about fibrinogen function.
