Product Specific Information

Store vial at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.

beta catenin antibody is directed against catenin beta-1 protein. A BLAST analysis was used to suggest cross-reactivity with catenin beta-1 protein from human, mouse, rat, bovine, Xenopus laevis, and Danio rerio at 100% based on homology with the immunizing sequence. Reactivity against homologues from other sources is not known.

Target Information

Beta-catenin, an adherens junction (AJ) protein, was originally identified as a component of cell-cell adhesion structures. AJs are necessary for the creation and maintenance of epithelial cell layers by regulating cell growth and adhesion between cells. Beta-catenin interacts with the cytoplasmic domain of E-cadherin and links E-cadherin to alpha-catenin, which in turn mediates anchorage of the E-cadherin complex to the cortical actin cytoskeleton. Studies show that Beta-catenin also binds to another cytoskeletal complex containing the adenomatous polyposis coli protein and microtubules, and interacts with several signaling pathways that include tyrosine kinases, phosphatases and Wnt/Wingless. The interplay between beta-catenin, cytoskeletal complexes and signaling pathways may regulate morphogenesis. Beta-catenin is expressed in several hair follicle cell types, basal and peripheral matrix cells, and cells of the outer and inner root sheats. A pathological role of beta-catenin has been identified in pilomatrixoma (PTR), medulloblastoma (MDB), colorectal cancer (CRC), ovarian cancer, and tumor development. In the nucleus, beta-catenin serves to co activate a family of Lef/Tcf transcription factors that stimulate transcription of target genes including those encoding cyclin D and c-myc that promote cell proliferation. The influence on cell proliferation is the molecular basis for the role of beta-catenin in tumorgenesis, specifically, solid tumors of the breast, colon, liver, lung, gastric, prostate, and skin.
