Differential structural requirements for fibrinogen binding to platelets and to endothelial cells
The cytoadhesins represent a group of RGD receptors that belongs to the integrin superfamily of adhesion molecules. Members of this cytoadhesin family include the platelet GPIIb-IIIa and the vitronectin receptors. These glycoproteins share the same beta-subunit, which is associated with different alpha subunits to form an alpha/beta heterodimer. In the present study, we have analyzed the fine r...
متن کاملFibrinogen Binding to Human Platelets*
Platelet-activating factor 1-0-alkyl-2-acetyl-englycero-3-phosphocholine (PAF-acether) triggers exposure of fibrinogen binding sites on platelets via binding to specific receptors. Comparison of 13H]PAFacether binding with lZ8I-fibrinogen binding shows that the rate with which PAF-acether binds to a number of receptors and not the degree of receptor occupancy determines how much fibrinogen bin...
متن کاملFibrinogen Binding to Human Blood Platelets :
Recent evidence suggests that fibrinogen binding to platelets is mediated by the 1 2 carboxyterminal amino acid residues of the ‘y chain. Because human plasma fibrinogen _y chains differ in mol wt and carboxyterminal amino acid sequence. we examined the effect of such y chain heterogeneity on platelet-fibrinogen interactions. using two fibrinogens of distinct composition. separated by ion excha...
متن کاملArginyl-glycyl-aspartic acid sequences and fibrinogen binding to platelets.
Human fibrinogen has an Arg-Gly-Asp-Ser (RGDS) sequence at residues 572-575 of its A alpha-chain. Although RGDS-containing peptides inhibit fibrinogen binding to stimulated platelets, these peptides also inhibit platelet binding of human fibrinogen fragment X and rat fibrinogen, which lack RGDS sequences corresponding to A alpha 572-575. Thus competition between free RGD-containing peptides and...
متن کاملCorrelation between fibrinogen binding to human platelets and platelet aggregability.
Fibrinogen is essential for aggregating platelets with adenosine diphosphate (ADP) and was recently shown to bind to platelets stimulated with ADP. The present work confirms the specific and saturable nature of the platelet-fibrinogen interaction. Binding of 125iodine-labeled fibrinogen to human gel-filtered platelts was maximal at 1 min, and the receptors were saturated when the fibrinogen con...
