Cat. No. :	VTN-2709H
Description :	Vitronectin, also known as VTN, is a member of the pexin family. It is an abundant glycoprotein found in serum the extracellular matrix and promotes cell adhesion and spreading. Vitronectin is a secreted protein and exists in either a single chain form or a cleaved, two chain form held together by a disulfide bond. Vitronectin consists of three domains: the N-terminal Somatomedin B domain, a central domain with hemopexin homology, and a C-terminal domain also with hemopexin homology. The Somatomedin B domain is a close knit disulfide knot and binds to plasminogen activator inhibitor-1 (PAI-1) and stabilizes it. An RGD sequence which is a binding site for membrane bound integrins is also found in Vitronectin. As a component of platelets, Vitronectin serves to regulate proteolysis initiated by plasminogen activation, interacts with the urokinase receptor, and binds to several serpin serine protease inhibitors as well. Accordingly, Vitronectin is suggested to be.
