Analysis of rodent platelet glycoprotein IIb: evidence for evolutionarily conserved domains and alternative proteolytic processing.
Recently, the full-length primary amino acid sequence for human glycoproteins (GP) IIb and IIIa have been derived from their respective cDNAs. Potential functional domains within these proteins have been proposed based primarily on homology with similar domains in other proteins having known biologic function. To further understand the relationship between structure and function of the platelet...

متن کاملCalcium regulation of the platelet membrane glycoprotein IIb-IIIa complex.
Platelet membrane glycoproteins (GP) IIb and IIIa form a Ca2+-dependent, heterodimer complex (GP IIb-IIIa) in detergent solution. To determine whether these glycoproteins were complexed or dissociated in intact human platelets, 125I-labeled whole platelets were lysed with an EDTA/Triton X-100 buffer, which stabilized both the complexed and dissociated forms of GP IIb and GP IIIa. The percentage...

متن کاملPlatelet Glycoprotein IIb/IIIa Inhibitors
Glycoprotein IIb/IIIa (GPIIb-IIIa) complexes (integrin aIIbb3) mediate platelet aggregation by binding fibrinogen or von Willebrand factor (vWF), protein cofactors that form bridges between adjacent platelets. The cross-linked adhesive proteins assemble platelets into the aggregate. Agents that block the function of the GPIIb-IIIa complex of platelets constitute a powerful new generation of ant...
