Specificity / Sensitivity

Phospho-MDM2 (Ser166) Antibody detects endogenous levels of MDM2 only when phosphorylated at Ser166. Phospho-MDM2 (Ser166) Antibody能够检测内源性丝氨酸(166位)磷酸化的MDM2蛋白。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser166 of human MDM2. Antibodies are purified by protein A and peptide affinity chromatography. 该多克隆抗体是由合成的人源的针对MDM2蛋白丝氨酸(166位)的磷酸化肽段免疫动物,采用蛋白A和多肽亲和层析技术生产的。

MDM2, a ubiquitin ligase for p53, plays a central role in regulation of the stability of p53 (1). Akt-mediated phosphorylation of MDM2 at Ser166 and Ser186 increases its interaction with p300, allowing MDM2-mediated ubiquitination and degradation of p53 (2-4). Phosphorylation of MDM2 also blocks its binding to p19ARF, increasing the degradation of p53 (3). MDM2,一种p53泛素连接酶,在p53稳定性的调节中至关重要(1)。Akt介导的MDM2苏氨酸166和168位磷酸化增加了它和p300的相互作用,允许MDM2介导的泛素化和p53降解(2-4)。MDM2的磷酸化也阻碍其结合p19ARF,促进p53降解(3)。
