| 背景 | β-Catenin is a key downstream effector in the Wnt signaling pathway (1). It is implicated in two major biological processes in vertebrates: early embryonic development (2) and tumorigenesis (3). CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41 (7). Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines (8). |

Western blot analysis of total cell lysates from SK-N-MC cells, treated with forskolin (FSK) for 30 minutes, or the lysate was treated with λ phosphatase for 1 hour, using Phospho-β-Catenin (Ser552) Antibody (upper) or β-Catenin Antibody (Amino-terminal Antigen) #9581 (bottom). 使用Phospho-β-Catenin (Ser552) 抗体(上)或 β-Catenin 抗体 (氨基末端抗原) #9581 (底)对经过forskolin（FSK）处理30分钟或λ 磷酸酶处理1小时的SK-N-MC细胞提取物进行western blot分析。 | |
COS-7 cells were transfected with cDNAs for the DYKDDDDK-tagged wild type (WT) β-catenin or for Ser-to-Ala β-catenin mutants as indicated. Cells were stimulated with 10 mM forskolin (FSK) for 5 minutes and lysed. β-catenin or its mutants were immunoprecipitated with DYKDDDDK Tag Antibody (Binds to same epitope as Sigmas Anti-FLAG® M2 Antibody) #2368 and analyzed by western blotting with Phospho-β-Catenin (Ser552) Antibody #9566, Phospho-β-Catenin (Ser675) Antibody #9567, or DYKDDDDK Tag Antibody as indicated (Figures provided by Drs. Sebastien Taurin and Nickolai Dulin, Department of Medicine / Pulmonary, The University of Chicago). DYKDDDDK标记的野生型（WT）β-catenin或Ser-to-Ala β-catenin突变体cDNA转染COS-7细胞后如图所示。10 mM forskolin (FSK)处理细胞5分钟后，溶解的β-catenin 或其突变体用DYKDDDDK Tag抗体免疫沉淀（结合到same epitope as Sigmas Anti-FLAG® M2抗体）#2368并使用Phospho-β-Catenin (Ser552)抗体 #9566, Phospho-β-Catenin (Ser675) 抗体#9567, 或 DYKDDDDK Tag抗体进行western blot实验。（图片由芝加哥大学Department of Medicine / Pulmonary, Sebastien Taurin和 Nickolai Dulin博士提供）。 |
