  • 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. 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 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
    • 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
      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.

    • ab23516 staining Fibronectin in porcine trachea by Immunohistochemistry (Frozen sections).
      Tissue was fixed in acetone and blocked using 1% BSA with 10% donkey serum for 2 hours at room temperature. Samples were then incubated with ab23516 at a 1/100 dilution for 18 hours at 4°C. The secondary used was an Alexa-Fluor® 555 donkey anti-sheep IgG (H+L), used at a 1/200 dilution.
