Background:

Catenin δ-1 (p120 catenin) has an amino-terminal coiled-coil domain followed by a regulatory domain containing multiple phosphorylation sites and a central Armadillo repeat domain of ten linked 42-amino acid repeats. The carboxy-terminal tail has no known function. Catenin δ-1 fulfills critical roles in the regulation of cell-cell adhesion as it regulates E-cadherin turnover at the cell surface to determine the level of E-cadherin available for cell-cell adhesion. Catenin δ-1 has both positive and negative effects on cadherin-mediated adhesion. Actin dynamics are also regulated by catenin δ-1, which modulates RhoA, Rac, and cdc42 proteins. Analogous to β-catenin, catenin δ-1 translocates to the nucleus, although its role at this location is unclear. Many studies show that catenin δ-1 is expressed irregularly or is absent in various types of tumor cells, suggesting that catenin δ-1 may function as a tumor suppressor.

Specificity:

Catenin-δ1 (phospho-Y228) polyclonal antibody detects endogenous levels of Catenin-δ1 protein only when phosphorylated at Tyr228.
