ModBase 3D Structure for Q7ZU14
Species Reactivity
Human, Rat, Mouse
This antibody was cross-adsorbed to phospho-tyrosine coupled to agarose before affinity purification using phospho- beta -Catenin (Tyr-142) peptide (without carrier). The antibody detects a 92kDa* protein corresponding to the molecular mass of beta -Catenin on SDS-PAGE immunoblots of Hct116 src transformed cells treated with pervanadate, but not in control cells. Similar results were observed in other pervanadate-treated cell lines, such as A431 and human endothelial cells.
Affinity Purified
Rabbit polyclonal, affinity-purified antibody is supplied in 100 ul phosphate-buffered saline, 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide.
Phospho-beta-Catenin (Tyr-142) synthetic peptide (coupled to KLH) corresponding to amino acid residues around tyrosine 142 of human beta-Catenin. This peptide sequence has one amino acid difference from a sequence around tyrosine 133 of human gamma-Catenin. These human sequences are highly conserved in rat and mouse beta-Catenins.
Preparation and Storage
Store at -20 degree C. Do not aliquot. Stable for 1 year.
Other Notes
Small volumes of anti-ctnnb1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
anti-ctnnb1 antibody
beta-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 ECadherin eliminate catenin binding and result in a loss of cell adhesion. 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. 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 transcriptional to the adhesive role of beta-Catenin. Src family kinases can also phosphorylate tyrosine 654 in the C terminal armadillo repeat of beta-Catenin. This phosphorylation regulates beta-Catenin binding to E cadherin. Thus, sitespecific tyrosine phosphorylation of beta-Catenin may regulate specific protein-protein interactions leading to changes in cell adhesion.
