      • Cold-insoluble globulin
      Background InformationFibronectin (FN), or in earlier literature also known as Cold-insoluble globulin (CIG), and is encoded by the gene named FN1/FN is an extracellular matrix protein. Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin. Fibronectins are involved in cell adhesion, cell motility, opsonization, wound healing, and maintenance of cell shape. Fibronectin also plays an important role in bone development and bone structure formation. Additionally, when fibronectin binds the protein anastellin it forms a multiprotein complex termed superfibronectin that has been shown to inhibit tumor growth, angiogenesis and metastasis. Fibronectin protein can be found extracellularly as well as intracellularly. There are multiple isoforms produced by alternative splicing. Plasma fibronectin (a soluble dimeric form) is secreted by hepatocytes into the blood. Cellular fibronectin (dimeric or cross-linked multimeric forms), are made by fibroblasts, epithelial and other cell types, and is deposited as fibrils in the extracellular matrix.
