This antibody might cross react with another overexpressed phospho-tyrosine protein.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nPolyclonal antibodies are produced by immunizing animals with synthetic phosphopeptides corresponding to residues surrounding Tyr228 of human\/mouse catenin δ-1. Antibodies are purified by peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nCatenin 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 (1). 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 (2). Catenin δ-1 has both positive and negative effects on cadherin-mediated adhesion (3). Actin dynamics are also regulated by catenin δ-1, which modulates RhoA, Rac, and cdc42 proteins (1). 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 (4). Catenin δ-1 is phosphorylated at multiple tyrosine sites along its sequence both and (5). High levels of catenin δ-1 phosphorylated at Tyr228 are commonly seen in several carcinoma cell lines. EGFR signaling induces catenin δ-1 phosphorylation at Tyr228, with the phosphorylated protein becoming localized at adherens junctions although phosphorylation is not essential in junction formation (6).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nBCDS2; Cadherin-associated Src substrate; CAS; catenin (cadherin-associated protein), delta 1; catenin delta 1; Catenin delta-1; CTND1; CTNND; CTNND1; KIAA0384; p120; p120 catenin; p120(cas); p120(ctn); P120CAS; P120CTN\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 95, 100\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46798059143337,"sku":"2911S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2911s","provider":"Iright","version":"1.0","type":"link"}
