Specificity / Sensitivity

Phospho-Catenin δ-1 (Tyr904) Antibody detects endogenous levels of catenin δ-1 protein only when phosphorylated at Tyr904. The antibody might cross react with another overexpressed phospho-tyrosine protein.

Phospho-Catenin δ-1 (Tyr904) 抗体仅能识别在904位酪氨酸磷酸化后的内源性catenin δ-1蛋白。该抗体可能会与其他过表达的磷酸化酪蛋白发生交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with synthetic phosphopeptides corresponding to residues surrounding Tyr904 of human/mouse catenin δ-1. Antibodies are purified by peptide affinity chromatography.

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 (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 (p120 catenin)氨基末端是一个螺旋环-螺旋结构域,随后是带有多个磷酸化位点和一个由42个氨基酸重复10次组成的一个中心Armadillo重复结构域。羧基端功能尚不清楚(1)。Catenin δ-1调控细胞表面E-cadherin翻转以使E-cadherin达到足以形成细胞-细胞黏附,从而发挥Catenin δ-1调控细胞黏附的作用(2)。Catenin δ-1在cadherin-介导的细胞黏附过程中同时扮演正向和负向调控作用(3)。catenin δ-1同时也会调控肌动蛋白丝的动力变化过程,以调节RhoA,Rac和cdc42蛋白(1)。类似于β-catenin,catenin δ-1会转移到细胞核,尽管这种转移的目的尚不清楚。许多研究表明在多种癌细胞中,catenin δ-1表达异常或缺失,提示catenin δ-1可能作为一种抑癌因子(4)。

Phosphorylation of Tyr904 on Catenin-δ-1 was identified at Cell Signaling Technology (CST) using PhosphoScan®, a CST's LC-MS/MS platform for phosphorylation site discovery (5).
