| Rabbit |
| Phospho-_-Catenin (Tyr-550) synthetic peptide (coupled to KLH) corresponding to amino acid residues around tyrosine 550 of human _-Catenin. |
| Tyr-550 |
| Polyclonal |
| #REF! |
| IgG |
| Antigen Affinity purification |
| PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol |
| Storage at -20C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20C. |

| Plakoglobin, JUP, Desmoplakin III, Desmoplakin-3, catenin gamma1 |
| Plakoglobin (_-Catenin) is a catenin family member identified as a component of desmosomes. _-Catenin has high homology to _-catenin and, like _-catenin, it can associate with the cadherins, E-cadherin and N-cadherin. One molecule of _-catenin and at least one molecule of _-catenin and _-Catenin simultaneously bind to a single cadherin molecule. A 19-amino acid sequence of desmoglein was found to be critical for binding of _-Catenin. Similar catenin-binding domains found in cadherins, suggest a common mechanism for _-Catenin localization to both adherens junctions and desmosomes. Phosphorylation of tyrosine residues in _-Catenin can modify its interactions with other proteins. Phosphorylation of tyrosine 644 decreases _-Catenin association with _-catenin, but increases binding to desmoplakin. Fer kinase can phosphorylate tyrosine 550, which increases _-Catenin binding to _-catenin. Thus, tyrosine phosphorylation may be important for regulation of _-Catenin protein-protein interactions within desmosomal complexes. |
