Fibronectins play a role in cell adhesion, motility, wound healing, and the maintenance of cell shape. Fibronectins bind to cell surfaces via interactions with integrins and various molecules such as collagen, fibrin, heparin, DNA, and actin (PMID: 3326130). Cellular interaction with fibronectin (FN1) promotes cell cycle progression and proliferation by influencing cyclins.
What is the molecular weight of FN1?
The molecular weight of FN1 is 220 kDa.
What is the tissue specificity of FN1?
FN1 is a large glycoprotein that exists in both a soluble form in plasma (plasma FN1) and other body fluids and an insoluble form in the extracellular matrix (cellular FN1) (PMID: 21923916). Plasma FN1, or the dimeric form, is secreted by hepatocytes, whereas cellular FN1, the dimeric or cross-linked multimeric form, is produced by fibroblasts and epithelial cells and deposited as fibrils in the extracellular matrix.
What are the post-translational modifications of FN1?
FN1 is often sulfated and its C-terminal NC1 peptide, anastellin, is produced as a result of proteolytic processing and can inhibit tumor growth, angiogenesis, and metastasis by activating p38 MAPK and inhibiting lysophospholipid signaling (PMID: 11209058).
What is FN1's role in embryogenesis?
Fibronectin has a crucial role in the development of the left-right body axis during embryogenesis (PMID: 21466802).
What is FN1's involvement in disease?
Fibronectin glomerulopathy is a kidney disease that eventually leads to end-stage renal disease and is caused by mutations in the FN1 gene. Mutations in FN1 lead to the production of abnormal fibronectin protein that is deposited in the glomeruli of the kidney (PMID: 18268355).
