Role of Thrombospondin-1 in Control of von Willebrand Factor Multimer Size in Mice
1 May 2004
Abstract excerpt
Plasma von Willebrand factor (VWF) is a multimeric glycoprotein from endothelial cells and platelets that mediates adhesion of platelets to sites of vascular injury. In the shear force of flowing blood, however, only the very large VWF multimers are effective in capturing platelets. The multimeric size of VWF can be controlled by proteolysis at the Tyr(842)-Met(843) peptide bond by ADAMTS13 or cleavage of the...
