Applications

Target

• FunctionFibronectins 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.
  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 specificityPlasma 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 diseaseGlomerulopathy with fibronectin deposits 2 (GFND2) [MIM:601894]: Genetically heterogeneous autosomal dominant disorder characterized clinically by proteinuria, microscopic hematuria, and hypertension that leads to end-stage renal failure in the second to fifth decade of life. Note=The disease is caused by mutations affecting the gene represented in this entry.
• Sequence similaritiesContains 12 fibronectin type-I domains.
  Contains 2 fibronectin type-II domains.
  Contains 16 fibronectin type-III domains.
• Developmental stageUgl-Y1, Ugl-Y2 and Ugl-Y3 are present in the urine from 0 to 17 years of age.
• Post-translational
  modificationsSulfated.
  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).
  Phosphorylation sites are present in the extracellular medium.
  Proteolytic processing produces the C-terminal NC1 peptide, anastellin.
• Cellular localizationSecreted > extracellular space > extracellular matrix.

  Immunocytochemistry/ Immunofluorescence-Fibronectin antibody [Fn-3](ab18265)
  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.

The cells were fixed in paraformaldehyde, permeabilised in Triton X-100 and then blocked using 1% serum for 30 minutes at 24°C. Samples were then incubated with primary antibody at 1/500 for 1 hour at 24°C. The secondary antibody used was a goat polyclonal conjugated to Alexa Fluor® 546 used at a 1/1000 dilution.
