General description

Catenins are proteins found in complexes with cadherin cell adhesion molecules of animal cells. The first two catenins that were identified became known as α-catenin and β-catenin. α-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.
When β-catenin was sequenced it was found to be a member of the armadillo family of proteins. These proteins have multiple copies of the so-called armadillo repeat domain which is specialized for protein-protein binding. An increase in β-catenin production has been noted in those people who have Basal Cell Carcinoma and leads to the increase in proliferation of related tumors. When β-catenin is not associated with cadherins and α-catenin, it can interact with other proteins such as Catenin Beta Interacting Protein 1 (ICAT) and adenomatosis polyposis coli (APC).
Recent evidence suggests that β-catenin plays an important role in various aspects of liver biology including liver development (both embryonic and postnatal), liver regeneration following partial hepatectomy. HGF-induced hepatpomegaly, liver zonation, and pathogenesis of liver cancer.

Specificity

Recognizes active form of β-catenin, dephosphorylated on Ser37 or Thr41.
The antibody eptiope is 100% conserved in zebrafish.

Immunogen

Epitope: The epitope corresponds to amino acid residues 36-44 (HSGATTTAP) of human β-catenin.
Fusion protein corresponding to residues 1-100 of human β-catenin with a c-terminal histidine tag

Application

Research Sub Category
Transcription Factors
Anti-Active-β-Catenin (anti-ABC) Antibody, clone 8E7 is a well characterized Mouse Monoclonal Antibody. This highly published mAb also known as Anti-Catenin beta-1 readily detects beta-Catenin & has been validated in FC, ICC, IHC, IHC(P) & WB.
Immunocytochemistry: This antibody was used in immunocytochemistry and showed positive staining on the membrane and cytosol.
This antibody has also been reported by an independent laboratory to show positive immunostaining for beta-catenin in LiCl-treated 293T cells fixed with methanol (Staal, Frank J. T., 2002).

Flow Cytometry: This antibody was used in flow cytometry at an optimal 1 μg/mL concentration.

Immunohistochemistry: This antibody was used in immunohistochemistry on a colorectal carcinoma tissue array at a 1:300 dilution.
This antibody has also been reported by an independent laboratory to detect beta-catenin in mouse embryo sections (Van Noort, M., 2002).
