MeOH fixed HeLa cells were stained with α-E-Catenin (clone 1G5) at 1 µg/ml. Goat-anti mouse Alexa Fluor® 594 was used as a secondary antibody and the cells were counterstained using DAPI. -
30 µg of A431 cell lysate was loaded and subjected to electrophoresis. Membrane was blotted using α-E-Catenin (clone 1G5) at 10 µg/ml followed by a fluorescent labeled goat anti-mouse IgG secondary.

α-catenin associates with the cytoplasmic domain of a variety of plasma membrane spanning cadherins that mediate cell-cell adhesion. The association of catenins to cadherins produces a complex that is linked to the actin filament network, which seems to be of primary importance for their cell-adhesion properties. Catenin can associate with both E- and N-cadherins. It was originally thought 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 α-catenin was shown not to bind to F-actin when assembled in the complex suggesting a more complex, dynamic linkage between actin and these 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.

ICC - Quality tested
WB - Verified - Recommended Usage
-
Each lot of this antibody is quality control tested by immunocytochemistry. For immunocytochemistry, a concentration range of 0.1 - 10 μg/ml is recommended. For Western blotting, the suggested use of this reagent is 5.0 - 10 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.
It is also recommended using EDTA-based solutions for dissociating attachment-dependent cell lines. -

Antigen Details
- Structure
- A 102 kD member of the α-Catenin family composed primarily of alpha helical bundles. It contains three vinculin homology domains, a vinculin binding region, an actin binding domain, and a dimerization domain.
- Distribution
-
Cytoplasm, cytoskeleton, cell junctions, adherens junctions, cell membrane, peripheral membraine protein, and the cytoplasmic side.
- Function
- Involved in endothelial cell survival, migration, contact-dependent growth inhibition, hemophilic adhesion, signal transduction, Wnt signaling, and cell junction organization.
- Interaction
- α-catenin binds to β-catenin. Cadherin binds to the p120-catenin and β-catenin. This cadherin-catenin complex interacts with the actin cytoskeleton. α-catenin can also bind vinculin, then associate with actin nucleating proteins.

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
