ターゲット情報

  • 機能
    Associates with the cytoplasmic domain of a variety of cadherins. The association of catenins to cadherins produces a complex which is linked to the actin filament network, and which seems to be of primary importance for cadherins cell-adhesion properties. Can associate with both E- and N-cadherins. Originally believed to be a stable component of E-cadherin/catenin adhesion complexes and to mediate the linkage of cadherins to the actin cytoskeleton at adherens junctions. In contrast, cortical actin was found to be much more dynamic than E-cadherin/catenin complexes and CTNNA1 was shown not to bind to F-actin when assembled in the complex suggesting a different linkage between actin and adherens junctions components. The homodimeric form may regulate actin filament assembly and inhibit actin branching by competing with the Arp2/3 complex for binding to actin filaments. May play a crucial role in cell differentiation.
  • 組織特異性
    Expressed ubiquitously in normal tissues.
  • 配列類似性
    Belongs to the vinculin/alpha-catenin family.
  • 翻訳後修飾
    Sumoylated.
  • 細胞内局在
    Cell membrane and Cytoplasm > cytoskeleton. Cell junction > adherens junction. Cell membrane. Cell junction. Found at cell-cell boundaries and probably at cell-matrix boundaries.

  • Ab51032 (1:100) staining human alpha 1 Catenin in human breast carcinoma tissue by immunohistochemistry using paraffin embedded tissue.
  • ICC/IF image of ab51032 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 (ab51032, 1µg/ml) overnight at +4°C. The secondary antibody (green) was anti-rabbit Alexa Fluor® 488 (IgG H+L; ab150077) 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.

  • ICC/IF image of Anti-alpha 1 Catenin antibody [EP1793Y] (ab51032) stained mouse ES cells. The cells were fixed in 1:1 methanol/acetone, permeabilized using 0.1% Triton X, and blocked with 1% serum in PBS for 30 minutes. The cells were then incubated with ab51032 at a 1/100 dilution for 16 hours at 4oC. The secondary antibody was a Goat Anti-Rabbit Alexa Fluor 488 (IgG H&L;  ab150077) used at a 1/500 dilution.

  • Overlay histogram showing MCF7 cells stained with ab51032 (red line). The cells were fixed with 4% PFA (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab51032, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was goat anti-rabbit DyLight® 488 (IgG H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in MCF7 cells fixed with 80% methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

Thank you for contacting us.

This product was tested with rat, human and mouse samples only; xenopus was never tried. We can however predict, it will be fine for Xenopus as well because the N-terminal end of Xenopus protein (http://www.uniprot...
