Immunocytochemical labeling of phosphorylated β-Catenin in paraformaldehyde-fixed and NP-40-permeabilized rabbit spleen fibroblasts. The cells were labeled with mouse monoclonal β-Catenin and rabbit polyclonal β-Catenin (Tyr-142) antibodies, then the antibodies were detected using appropriate secondary antibodies conjugated to Cy3.

Western blot analysis of Hct116 src transformed cells (20 µg/lane) serum starved overnight or treated with pervanadate (1 mM) for 30 min. The blot was probed with anti-β-Catenin or anti-β-Catenin (Tyr-142).

Target

β-Catenin (Tyr-142)[γ-Catenin (Tyr-133)]

Target Description

β-Catenin is a 92 kDa protein that binds to the cytoplasmic tail of E-Cadherin. The cadherins, transmembrane adhesion molecules, are found with catenins at adherens junctions. Deletions in the cytoplasmic domain of E-Cadherin eliminate catenin binding and result in a loss of cell adhesion. Tyrosine phosphorylation of β-Catenin can regulate its interaction with critical components of adherens junctions. Both Fer and Fyn kinases phosphorylate tyrosine 142 in vitro. Overexpression of these kinases in epithelial cells disrupts interactions between α- and β-Catenins. The phosphorylation of tyrosine 142 may act as a switch from the transcriptional to the adhesive role of β-Catenin. Src family kinases can also phosphorylate tyrosine 86 and 654 in β-Catenin. The Tyr-654 phosphorylation regulates β-Catenin binding to E-cadherin. Thus, site-specific tyrosine phosphorylation of β-Catenin may regulate protein-protein interactions leading to changes in cell adhesion.

Antigen

Phospho-β-Catenin (Tyr-142) synthetic peptide (coupled to KLH) corresponding to amino acid residues around tyrosine 142 of human β-Catenin. This peptide sequence has one amino acid difference from a sequence around tyrosine 133 of human γ-Catenin. These human sequences are highly conserved in rat and mouse β- and γ-Catenins.

Species Reactivity

Human, Mouse, Rat

Storage

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Physical State

Liquid

Buffer

PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Dilution Ranges

Conjugate

Unconjugated

Specificity

This antibody was cross-adsorbed to phospho-tyrosine coupled to agarose before affinity purification using phospho-β-Catenin (Tyr-142) peptide (without carrier). The antibody detects a 92kDa* protein corresponding to the molecular mass of β-Catenin on SDS-PAGE immunoblots of Hct116 src-transformed cells treated with pervanadate, but not in control cells. Similar results were observed in pervanadate-treated A431 and human endothelial cells.
