Using Phospho‐Motif Antibodies to Determine Kinase Substrates

Figure 18.20.1 The specificity of phospho‐motif antibodies. HeLa cells were serum‐starved for 24 hr prior to being stimulated with 50 ng/ml IGF‐1 or 100 nM PMA for 10 min. Lysates were immunoblotted with anti‐Akt/PKB phospho‐motif (left panel

【求助】关于gsk3-beta功能的疑问

下调不能说明活性降低，因为决定GSK3-beta的活性的还与其磷酸化的比例和磷酸化的位点有关。所以你除了要做GSK3-beta总的蛋白表达之外，还要做磷酸化的GSK3-beta的蛋白表达。 （2）应该活性形式和非活性形式都做。一般来讲，GSK3-beta在Ser9位点磷酸化之后活性收到抑制，而在216位点磷酸化之后，其活性收到加强。因此建议将GSK3-beta的两个磷酸化位点都做了，另外还要同时检测GSK3-beta的总蛋白表达，这样才能全面的说明问题。

3.1 and 3.6 ). This will provide a “specific activity” measurement relative to total protein in the cell, and is themost accurate measure of total GSK3 activity, or2. Immunoblot using antibodies to phospho-Ser21 (GSK3a)or phospho-Ser9 (GSK3b) (see Sections 3.1 –
