Plakoglobin (γ-Catenin) is a catenin family member identified as a component of desmosomes. γ-Catenin has high homology to β-catenin and, like β-catenin, it can associate with the cadherins, E-cadherin and N-cadherin. One molecule of α-catenin and at least one molecule of β-catenin and γ-Catenin simultaneously bind to a single cadherin molecule. A 19-amino acid sequence of desmoglein was found to be critical for binding of γ-Catenin. Similar catenin-binding domains found in cadherins, suggest a common mechanism for γ-Catenin localization to both adherens junctions and desmosomes. Phosphorylation of tyrosine residues in γ-Catenin can modify its interactions with other proteins. Phosphorylation of tyrosine 644 decreases γ-Catenin association with α-catenin, but increases binding to desmoplakin. Fer kinase can phosphorylate tyrosine 550, which increases γ-Catenin binding to α-catenin. Thus, tyrosine phosphorylation may be important for regulation of γ-Catenin protein-protein interactions within desmosomal complexes.

Western blot analysis of anti-γ-Catenin (C-terminal) immunoprecipitates from pervanadate-treated A431. The immunoprecipitates were untreated (lanes 1,3,7) or treated with alkaline phosphatase (lanes 2,4,8). The blots were probed with γ-Catenin (a.a. 545-555), γ-Catenin (Tyr-550) or γ-Catenin (C-terminal) antibodies. The anti-γ-Catenin (Tyr-550) was used in the presence of γ-Catenin (Tyr-550) (lane 5) or γ-Catenin (Tyr-644) (lane 6) peptides.

γ-Catenin synthetic peptide corresponding to amino acid residues 545 to 555 from human γ-Catenin. This peptide sequence is highly conserved in rat and mouse γ-Catenin.

This antibody was affinity purified using γ-Catenin (a.a. 545-555) peptide (without carrier). The antibody detects an 84kDa* protein corresponding to the molecular mass of γ-Catenin on SDS-PAGE immunoblots of A431 cells.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
