简介
Fibronectin is a polymorphic glycoprotein found in blood and tissues of vertebrates and in cultures of adherent vertebrate cells. There are several forms of fibronectin is composed of two high molecular weight subunits held together by forms found in tissues and on and around the surfaces of cultured cells. Soluble fibronectin is composed of two high molecular weight subunits held together by disulfide bonds. Insoluble fibronectin may be covalently cross-linked in larger complexes. Fibronectin has affinities for collagen, fibrin, heparin, and cell surfaces. in culture, fibronectin in growth medium may mediate attachment of cells to substratum, and fibronectin synthesized by cells may mediate adhesion to substratum. The widespread occurrence of fibronectin in basal lamina indicates that many different cell types in vivo abut against a fibronectin-containing matrix. Cultured transformed cells usually lack cell-surface …
