    Target

    • Function

      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.
    • Tissue specificity

      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.
    • Involvement in disease

      Glomerulopathy with fibronectin deposits 2
    • Sequence similarities

      Contains 12 fibronectin type-I domains.
      Contains 2 fibronectin type-II domains.
      Contains 16 fibronectin type-III domains.
    • Developmental stage

      Ugl-Y1, Ugl-Y2 and Ugl-Y3 are present in the urine from 0 to 17 years of age.
    • Post-translational
      modifications

      Sulfated.
      It is not known whether both or only one of Thr-2064 and Thr-2065 are/is glycosylated.
      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.
    • Cellular localization

      Secreted, extracellular space, extracellular matrix.

        ICC/IF image of ab18265 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab18265, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

      Question

      The above mentioned antibody can distinguish between the cellular and plasma FN. Hower neither the datasheet nor the references don't specify whether it recognises the EDA or EDB region (specific of cellular FN). Is there any possibility for your team to check, whether this is also specific to EDA as the IST-9 clone? If it isn't, then the suspicion is quite big, that it is EDB, which is recognised. If it is so, then Abcam could sell it as antibody against the Extra Domain B, being the only commercialised antibody of this kind. I think besides me, there are more scientists to use an EDB antibody. If for Abcam, there are no opportunity to check this, I can offer myself to make this assesment. We already have your EDA antibody to compare with. We have a well working silencing system for FN variants. I hope we can both benefit from this antibody!

      Asked on Oct 04 2006

      Answer

      Thank you for your enquiry. The Fn-3 clone recognizes a determinant on cellular but not plasma fibronectin. I am assuming this is the EDB region, although this is not explicitly stated in the reference I have. I will send this reference to you in a separate email. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
