General description

Anti-β-Catenin antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the 15B8 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c mouse immunized with recombinant chicken β-Catenin. β-Catenin, also known as Catenin βfamily.

Immunogen

recombinant chicken ß-Catenin

Application

Anti-β-Catenin antibody, Mouse monoclonal has been used in:
  • immunoblotting
  • immunofluorescence
  • immunohistochemistry
  • immunoprecipitation

Biochem/physiol Actions

β-Catenin plays a dual function in the cell including cell-cell adhesion and as a component of the Wnt (wingless) signaling pathway. In adherens junctions, β-Catenin associates with the cytoplasmic domain of the cadherin family adhesion receptors, anchoring them to the actin cytoskeleton and thus acting as structural protein. β-Catenin interacts with T cell factor (TCF)- family transcription factors to activate target genes. Wnt/β-catenin signaling interacts with several cellular pathways in context-dependent ways, including JakSTAT (Janus kinase−Signal transducer and activator of transcription) cytokine, TGFβ (transforming growth factor−β), DNA damage and the Hippo signaling pathways. Furthermore, β-Catenin is involved in embryonic morphogenesis and tumorigenesis and is tightly regulated by phosphorylation and further degradation by the ubiquitin-proteasome system.

Physical form

Beta-catenin and plakoglobin are closely related armadillo family proteins with shared and distinct properties; Both are associated with cadherins in actin-containing adherens junctions. Plakoglobin is also found in desmosomes where it anchors intermediate filaments to the desmosomal plaques. Beta-catenin, on
