• Product nameAnti-alpha 1 Catenin antibody
    See all alpha 1 Catenin primary antibodies
  • Description
    Rabbit polyclonal to alpha 1 Catenin
  • SpecificityReacts in dot blot immunoassay with alpha-catenin peptide amino acids 890-901 conjugated to BSA. Reacts with a 102 kD protein in extracts of Madin-Darby Bovine Kidney (MDBK) cultured cell line using immunoblotting. The antiserum shows no cross-reactivity with beta-catenin peptide (amino acids 768-781)conjugated to BSA. Specific staining in immunoblotting is inhibited by pre-incubating the diluted anti-serum with the alpha-catenin peptide.

  • Target

    • FunctionAssociates 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.
    • Tissue specificityExpressed ubiquitously in normal tissues.
    • Sequence similaritiesBelongs to the vinculin/alpha-catenin family.
    • Post-translational
    • Cellular localizationCell membrane and Cytoplasm > cytoskeleton. Cell junction > adherens junction. Cell membrane. Cell junction. Found at cell-cell boundaries and probably at cell-matrix boundaries.

    This antibody has not been tested in IP to our knowledge. We don't have any information as to whether the antibody will work in MDCK cells. All the information we have available on this antibody is on the datasheet.

    This antibody has been tested for cross-reactivity against mammalian species only, hence its reactivity with chicken is unknown. It has not been specifically tested in the application you describe, however it would be expected to work with mammalian ce...
