Fibronectin 一次抗体 製品一覧
製品の詳細Mouse monoclonal [IST-9] to Fibronectin
特異性This antibody reacts with an epitope (PEDGIHELFP) located in the ED-A sequence of cellular fibronectin (it therefore only detects the cFN and not extracellular FN (plasma FN)). (Liao et al.) The ED-A segment can be included or omitted from the molecule depending on the pattern of splicing of the mRNA precursors. In transformed or tumour derived cells the ED-A segment is about 10-times higher than in FN from normal fibroblasts, and it may therefore be a significant marker for malignancy (Borsi et al., and others).

エピトープLiao et al: Clone IST-9, binds to the Ile43 and His44 residues within ED-A in a conformationally dependent fashion, implicating the loop region encompassing both residues as critical for mediating ED-A function. The conformational domain C-C'-E of rat EIIIA encompassing the His44 residue is crucial for constituting the IST-9 epitope.

機能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. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process, essential for osteoblast mineralization. Participates in the regulation of type I collagen deposition by osteoblasts.
Anastellin binds fibronectin and induces fibril formation. This fibronectin polymer, named superfibronectin, exhibits enhanced adhesive properties. Both anastellin and superfibronectin inhibit tumor growth, angiogenesis and metastasis. Anastellin activates p38 MAPK and inhibits lysophospholipid signaling.
組織特異性Plasma FN (soluble dimeric form) is secreted by hepatocytes. Cellular FN (dimeric or cross-linked multimeric forms), made by fibroblasts, epithelial and other cell types, is deposited as fibrils in the extracellular matrix. Ugl-Y1, Ugl-Y2 and Ugl-Y3 are found in urine.

Forms covalent cross-links mediated by a transglutaminase, such as F13A or TGM2, between a glutamine and the epsilon-amino group of a lysine residue, forming homopolymers and heteropolymers (e.g. fibrinogen-fibronectin, collagen-fibronectin heteropolymers).
Phosphorylated by FAM20C in the extracellular medium.
Proteolytic processing produces the C-terminal NC1 peptide, anastellin.

Extracellular matrix expression pattern.
Fibronectin was displayed in microtissues after ten days. (Bar in A549/SV80 monocultures: 50 μm, bar in all other microtissues: 100 μm); Secretion of fibronectin could be observed in microtissues containing fibroblasts, whereas in all tumour cell monocultures no fibronectin secretion could be detected.
