Beta-catenin Rabbit anti-Human, Mouse, Polyclonal, Bethyl Laboratories

Description

• The recommended shelf life for this product is 1 year from date of receipt
• Application Note: For IHC, epitope retrieval with citrate buffer pH 6.0 is recommended for FFPE tissue sections
• Based on 100% sequence identity, this antibody is predicted to react with Rat, X
• laevis, Bovine and Dog 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 maintece 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.
