Product Specific Information
This antibody was cross-adsorbed to phospho-beta-Catenin (Tyr-654) peptide before affinity purification using phospho-beta-Catenin (Tyr-489) peptide (without carrier).
It detects 84 and 88 kDa proteins corresponding to gamma-Catenin and beta-Catenin, respectively, on SDS-PAGE immunoblots of A431 cells treated with pervanadate, but does not detect these proteins in control cells.
Target Information
beta-Catenin is a 92 kDa protein that binds to the cytoplasmic tail of E-Cadherin. Cadherins are transmembrane adhesion molecules found with catenins at adherens junctions.
Deletions in the cytoplasmic domain of E-Cadherin eliminate catenin binding and result in loss of cell adhesion.
Tyrosine phosphorylation of beta-Catenin regulates its interaction with adherens junction components.
Fer and Fyn kinases phosphorylate tyrosine 142 in vitro, and overexpression disrupts alpha-/beta-Catenin interactions.
Phosphorylation of tyrosine 142 may switch beta-Catenin between transcriptional and adhesive roles.
Src family kinases also phosphorylate tyrosine 86 and 654 in beta-Catenin, with Tyr-654 phosphorylation regulating E-Cadherin binding.
Site-specific tyrosine phosphorylation of beta-Catenin may thus control protein-protein interactions affecting cell adhesion.
