Background
Vitronectin also called serum spreading factor or complement S-protein, is a member of the pexin family (1). Found in serum and in tissues, Vitronectin exist in two forms; as a single chain (75kDa) and as a clipped form composed of two chains (65kDa and 10kDa). Vitronectin promotes cell adhesion, spreading and migration through specific interactions with cellular integrins, and inhibits cytolysis by the complement C5b-9 complex (2-4). Vitronectin also interacts with several critical proteins that regulate thrombosis and fibrinolysis. Vitronectin is phosphorylated by PKA and CKII (5).
Limitations
