Target

  • FunctionIncorporated into fibronectin-containing matrix fibers. May play a role in cell adhesion and migration along protein fibers within the extracellular matrix (ECM). Could be important for certain developmental processes and contribute to the supramolecular organization of ECM architecture, in particular to those of basement membranes. Has been implicated in a role in cellular transformation and tumor invasion, it appears to be a tumor suppressor. May play a role in haemostasis and thrombosis owing to its ability to bind fibrinogen and incorporate into clots. Could play a significant role in modulating the neurotrophic activities of APP, particularly soluble APP.
  • Tissue specificityIsoform A and isoform B are only expressed in placenta. Isoform C and isoform D are expressed in a variety of tissues and cultured cells.
  • Involvement in diseaseNote=A chromosomal aberration involving FBLN1 is found in a complex type of synpolydactyly referred to as 3/3-prime/4 synpolydactyly associated with metacarpal and metatarsal synostoses. Reciprocal translocation t(12;22)(p11.2;q13.3) with C12orf2. Fibroblasts derived from a patient with synpolydactyly displayed alterations in the level of isoform D splice variant incorporated into the ECM and secreted into the conditioned culture medium. By contrast, the expression of isoform C was not perturbed in the patients fibroblasts. Furthermore, no aberrant polypeptides were detected in extracts of cultured patients fibroblasts. The translocation t(12;22) may result in haploinsufficiency of the isoform D splice variant, which could lead to the observed limb malformation.
    Note=Elevated expression and altered processing of FBLN1 protein is associated with human breast cancer.
  • Sequence similaritiesBelongs to the fibulin family.
    Contains 3 anaphylatoxin-like domains.
    Contains 9 EGF-like domains.
  • Developmental stageWidely expressed during embryonic development. Prominent in the matrix of the leptomeningeal anlage, in basement membranes of the neuroepithelium and the perineurium of peripheral nerves. In embryos of gestational week (gw) 4, staining was observed in the early mesenchymal bone anlagen. In gw 6.5 and 8, all perichondrial structures showed expression but the chondrocytes themselves showed no staining. In gw 10, expression is prominent in the interterritorial matrix surrounding the hypertrophic chondrocytes.

  • Predicted band size : 77 kDa
    Fibulin 1 antibody (ab54652) at 1ug/lane + A-431 cell lysate at 25ug/lane.
  • ICC/IF image of ab54652 stained HeLa cells. The cells were 4% formaldehyde (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 (ab54652, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879 Dylight 488 goat anti-mouse IgG (H+L) used at a 1/250 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.
