Validation Data Gallery

• 

  WB analysis using 28755-1-AP

  Non-treated PC-3 and Calyculin A treated PC-3 cells were subjected to SDS PAGE followed by western blot with 28755-1-AP (Phospho-FOXO3A (Ser315) antibody) at dilution of 1:1000 incubated at 4℃ overnight. The membrane was stripped and re-blotted with GAPDH antibody as loading control.

• 

  WB analysis using 28755-1-AP

  Non treated and Forskolin treated PC-3 cells were subjected to SDS PAGE followed by western blot with 28755-1-AP (Phospho-FOXO3A (Ser315) antibody) at dilution of 1:600 incubated at room temperature for 1.5 hours.

• 

  WB analysis using 28755-1-AP

Background Information

In mammalian cells, FoxO factors act as potent transcriptional activators that upregulate the expression of programs of genes involved in stress resistance, cell cycle arrest, differentiation, apoptosis, autophagy, and metabolism. FOXO3 has a key role in the maintenance of adult neural and hematopoietic stem cells. It also associates with extreme longevity in humans and regulates the homeostasis of adult stem cell pools in mammals, which may contribute to longevity. Phosphorylation inhibits FOXO3 nuclear translocation that is essential for its regulation and function. The calculated molecular weight of FOXO3 is 71 kDa,but some experiments analysis using a FOXO3a specific antibody showed the expression of a 90 kDa full length FOXO3a protein (Full) and a 40 kDa processed FOXO3a product (Short). 90 kDa FOXO3a protein is a phosphorylated via activation of PI3K (phosphatidylinositol 3-kinase) and Akt after INS stimulation, and translocate from the nucleus to the cytoplasm. (PMID: 19427386). IKBKE directly activates Akt and that Akt inhibits FOXO3a by phosphorylation of Ser32, Ser253 and Ser315.
