Hydrodynamic properties of a thromboxane A2/prostaglandin H2 antagonist binding site solubilized from human platelets
Abstract:
The hydrodynamic properties of a binding site for the thromboxane A2/prostaglandin H2 receptor antagonist 9,11-dimethylmethano-11, 12-methano-16-(3-iodo-4-hydroxyphenyl)-13, 14-dihydro-13-aza-15 alpha beta-omega-tetranor-thromboxane A2 (I-PTA-OH) were determined in solubilized membrane proteins from human platelets using the detergent 3-[(3-cholamidopropyl)-dimethylammonio] 1-propane-sulfonate (CHAPS). Gel filtration revealed a Stokes radius of 5.25 +/- 0.37 nm (n=9). Molecular weight determined by gel filtration assuming a spherical protein was 180,000-220,000 Daltons. Sedimentation through sucrose or glycerol gradients revealed a sedimentation coefficient of 6.3 +/- 0.2 Svedberg units (n=5). The molecular weight calculated using the Stokes radius and sedimentation coefficient was 140,000 Daltons. The frictional ratio f/fo was 1.4, corresponding to an axial ratio of 7:1.

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
