目标/特异性 | Phospho-FoxO1 (Thr24)/FoxO3a (Thr32) Antibody detects endogenous levels of FoxO1/FoxO3a only when phosphorylated at Thr24 of FoxO1 or Thr32 of FoxO3a. The antibody cross-reacts with phosphorylated FoxO4 at Thr28, but not with FoxO1 family members phosphorylated at other sites. Phospho-FoxO1 (Ser256) Antibody detects endogenous levels of FoxO1 only when phosphorylated at Ser256. The antibody cross-reacts with Fox04 phosphorylated at Ser193. Phospho-FoxO1 (Thr24)/FoxO3a (Thr32)/Fox04 (Thr28) (4G6) Rabbit mAb detects endogenous levels of FoxO1 when phosphorylated at Thr24, of FoxO3a when phosphorylated at Thr32 or FoxO4 when phosphorylated at Thr28. FoxO1 (C29H4) Rabbit mAb detects endogenous levels of total FoxO1 protein. The antibody does not detect exogenously expressed family members FoxO3a or FoxO4. Phospho-FoxO3a (Ser253) (D18H8) Rabbit mAb detects endogenous levels of FoxO3a only when phosphorylated at Ser253. This antibody may cross-react with FoxO1 when overexpressed and phosphorylated at Ser251 or FoxO4 when overexpressed and phosphorylated at Ser197. Phospho-FoxO3a (Ser318/321) Antibody detects endogenous levels of FoxO3a only when phosphorylated at Ser318/321. The antibody is expected to cross-react with FoxO1 when phosphorylated at Ser322/325 based on the peptide sequence. FoxO3a (D19A7) Rabbit mAb recognizes endogenous levels of total FoxO3a protein. The FoxO4 Antibody detects endogenous levels of FoxO4. The antibody is sensitive to phosphorylation within the antigen and preferrentially detects unphosphorylated FoxO4. |

背景 | Forkhead转录因子家族参与横纹肌肉瘤和急性白血病的发生(1-3)。这个家族的三个成员(FoxO1、 FoxO4和FoxO3a)与线虫的DAF-16蛋白有序列相似性。DAF-16调节IGFR1、PI3K和 Akt 参与的信号通路。活化的forkhead家族成员作为肿瘤抑制因子阻断细胞周期并促进凋亡。任何FoxO成员的高表达均可激活细胞周期的抑制因子 p27 Kip1。Forkhead转录因子也参与 TGF-β调控的 p21 Cip1上调过程,这个过程能够被 PI3K负向调节 (7)。Forkhead转录因子被Akt磷酸化修饰苏氨酸(24位)和丝氨酸(256和319位)后失活,导致其出核并抑制转录因子的活性(8)。Forkhead转录因子活性也可以被去乙酰化酶sirtuin(SirT1)(9)抑制。 |
