Phospho beta Catenin (Tyr 142) synthetic peptide (coupled to KLH) corresponding to amino acid residues around tyrosine 142 of human beta Catenin.
Tyrosine phosphorylation of beta Catenin can regulate its interaction with critical components of adherens junctions. Both Fer and Fyn kinases phosphorylate tyrosine 142 in vitro and overexpression of these kinases in epithelial cells disrupts interactions between alpha and beta Catenins. The phosphorylation of tyrosine 142 may act as a switch from the adhesive to the transcriptional role of beta Catenin. Thus, site specific tyrosine phosphorylation of beta Catenin may regulate specific protein protein interactions, leading to changes in cell adhesion.
Our Abpromise guarantee covers the use of ab27798 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/500. Detects a band of approximately 92 kDa (predicted molecular weight: 86 kDa).Can be blocked with Human beta Catenin (phospho Y142) peptide (ab42714). IP with beta catenin antibody is recommended, followed by probing with ab27798. This improve the distinction between beta Catenin Tyr 142 and gamma Catenin Tyr 133 (Swiss-Prot ID P14923).|
ICC/IF labeling of phosphorylated β-Catenin in paraformaldehyde-fixed and NP-40-permeabilized rabbit spleen fibroblasts. The cells were labeled with mouse monoclonal β-Catenin (left panel) and ab27798 antibodies, then the antibodies were detected using appropriate secondary antibodies conjugated to Cy3.
ab27798 staining beta Catenin (phospho Y142) in rat hippocampal neurons by Immunocytochemistry/ Immunofluorescence. The cells were pre-treated with pervanadate for 15 minutes before being fixed in paraformaldehyde and then blocked using 10% serum for 1 hour at 25°C. Samples were then incubated with primary antibody at 1/50 for 8 hours at 4°C. The secondary antibody used was a donkey anti-rabbit IgG conjugated to Alexa Fluor® 594 (red) ab150076) used at a 1/500 dilution. Hoestch was used to stain the cell nuclei (blue).
