Catenins are proteins found in complexes with cadherin cell adhesion molecules of animal cells. The first two catenins that were identified became known as alpha-catenin and beta-catenin. alpha-catenin can bind to beta-catenin and can also bind actin. beta-catenin binds the cytoplasmic domain of some cadherins. When beta-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 beta-catenin production has been noted in those people who have Basal Cell Carcinoma and leads to the increase in proliferation of related tumors. When beta-catenin is not associated with cadherins and alpha-catenin, it can interact with other proteins such as Catenin Beta Interacting Protein 1 (ICAT) and adenomatosis polyposis coli (APC). Recent evidence suggests that beta-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.
Applications:
Suitable for use in Western Blot. Other applications not tested.
Recommended Dilution:
Western Blot: 0.5-2ug/ml
Optimal dilutions to be determined by the researcher.
Positive Control:
HEK293 lysat
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
