Mapping the heparin-binding site on the 13-14F3 fragment of fibronectin.
Fibronectin, a multifunctional glycoprotein of the extracellular matrix, plays a major role in cell adhesion. Various studies have revealed that the human 13th and 14th fibronectin type III domains (labeled (13)F3 and (14)F3 here) contain a heparin-binding site. Mapping of the heparin-binding sites of (13-14)F3, (13)F3, and (14)F3 by NMR chemical shift perturbation, isothermal titration calorimetry, and molecular modeling show that (13)F3 provides the dominant heparin-binding site and that th...Expand abstract
