Studies on human and bovine platelet membrane glycoproteins
International Journal of Biochemistry, 1979Abstract 1. 1. We have re-evaluated the number of platelet membrane glycoproteins with use of sodium dodecyl sulfate—polyacrylamide gel electrophoresis and two highly sensitive detection techniques. 2. 2. The first involves incorporation of the fluorophore dansyi hydrazine into the carbohydrate moiety after post-electrophoresis periodate ...

Platelet membrane glycoproteins and their function: An overview
Blut, 1989The membrane glycoproteins (GP) of human platelets act as receptors that mediate two important functions, adhesion to the subendothelial matrix and platelet-platelet cohesion, or aggregation. Many of these glycoprotein receptors exist as noncovalently linked heterodimers, including those that belong to the supergene family of adhesion receptors called ...

Polymorphisms of Platelet Membrane Glycoproteins
2009Platelet glycoproteins (GPs) act as membrane receptors. Functions of GPs were well studied in GPIa/IIa (integrin α2β1), GPIb/IX/V, GPIIb/IIIa (integrin αIIbβ3), and GPVI. Each GP has a different role in the processes of physiological hemostasis and thrombus formation, such as platelet adhesion to the subendothelial matrix, firm adhesion with subsequent

Thrombin Interaction With Platelet Membrane Glycoprotein Ib
Seminars in Thrombosis and Hemostasis, 1996Platelet activation by low doses of thrombin allows the amplification thrombin formation and thereby plays an important role in the development of thrombi. Although thrombin-induced platelet activation is elicited via the cleavage of its specific receptor (TR), platelet membrane glycoprotein Ib (GPIb) is required for responses to low concentrations of ...

Thrombosis Research, 1989
Human platelets contain a single membrane glycoprotein which is susceptible to thrombin proteolysis, glycoprotein V. We have purified 1 mg of glycoprotein V from 10(13) platelets using a combination of gel filtration, hydroxylapatite and ion-exchange chromatographies. Glycoprotein V has a blocked amino-terminus.

Thrombin interaction with platelet membrane glycoprotein Ibα
Trends in Molecular Medicine, 2003The interaction of thrombin with platelet glycoprotein Ibalpha (GPIb alpha) is required for optimal platelet activation. The crystal structures of platelet GPIb alpha bound to thrombin reported by Dumas et al. and Celikel et al. both reveal the simultaneous interaction of GPIb alpha with thrombin exosites I and II but differ markedly regarding how the ...

[Platelet membrane glycoproteins in thrombocytapheresis and platelet concentrates].
Beitrage zur Infusionstherapie und Transfusionsmedizin = Contributions to infusion therapy and transfusion medicine, 1998Membrane glycoprotein (GP) expression on platelets changes during preparation of concentrates and storage. Recent studies proved that the increased expression of the GMP-140 (CD 62), a GP appearing on platelets after activation, correlates with the in vivo recovery of transfused platelets.

Glycoproteins of the Platelet Plasma Membrane
1985The glycoproteins of the platelet plasma membrane, in common with those of the plasma membranes of other cells, have an important role in the interaction of platelets with their environment and in particular in the platelet’s function of hemostasis.

Platelet Aggregation By Membrane Glycoprotein I
Thrombosis and Haemostasis, 1981It has been recently shown that platelet membrane components, particularly glycoproteins, have a lectin activity, thus mediating an aggregation of platelets. To obtain further evidences for a crucial role of glycoproteins in an aggregation mechanism,we have investigated the possibility that membrane glycoprotein can directly induce an aggregation of ...
