Target
-
FunctionTranscriptional activator which triggers apoptosis in the absence of survival factors, including neuronal cell death upon oxidative stress. Recognizes and binds to the DNA sequence 5'-[AG]TAAA[TC]A-3'.
-
Tissue specificityUbiquitous.
-
Involvement in diseaseNote=A chromosomal aberration involving FOXO3 is found in secondary acute leukemias. Translocation t(6;11)(q21;q23) with MLL/HRX.
-
Sequence similaritiesContains 1 fork-head DNA-binding domain.
-
Post-translational
modificationsIn the presence of survival factors such as IGF-1, phosphorylated on Thr-32 and Ser-253 by AKT1/PKB. This phosphorylated form then interacts with 14-3-3 proteins and is retained in the cytoplasm. Survival factor withdrawal induces dephosphorylation and promotes translocation to the nucleus where the dephosphorylated protein induces transcription of target genes and triggers apoptosis. Although AKT1/PKB doesn't appear to phosphorylate Ser-315 directly, it may activate other kinases that trigger phosphorylation at this residue. Phosphorylated by STK4 on Ser-209 upon oxidative stress, which leads to dissociation from YWHAB/14-3-3-beta and nuclear translocation. Phosphorylated by PIM1. -
Cellular localizationCytoplasm > cytosol. Nucleus. Translocates to the nucleus upon oxidative stress and in the absence of survival factors.

Immunoprecipitation - Anti-FOXO3A (phospho S253) antibody (ab31109)FOXO3A was immunoprecipitated using 0.5mg PC12 whole cell extract, 5µg of Rabbit polyclonal to FOXO3A and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
The antibody was incubated under agitation with Protein G beads for 10min, PC12 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab31109.
Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
Band: 63kDa; FOXO3A

Immunocytochemistry/ Immunofluorescence - Anti-FOXO3A (phospho S253) antibody (ab31109)ICC/IF image of ab31109 stained PC12 cells. The cells were 4% PFA fixed (10 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab31109, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue). -
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-FOXO3A (phospho S253) antibody (ab31109)Image from Guillen-Ahlers H et al, PLoS One. 2010 Feb 5;5(2):e9070, Fig 6.ab31109 staining FOXO3A in adenomas from ApcMin/+ mice (30 weeks old) by Immunohistochemistry (paraffin embedded sections). Intestines were opened longitudinally, cleaned, Swiss-rolled, fixed with periodate-lysine-paraformaldehyde, and embedded in paraffin.
Phosphorylated FOXO3A was identified utilizing ab31109, followed by HRP-conjugated goat-anti-rabbit IgG. All stains were then developed in 3, 3′-diaminobenzidine and a haematoxylin counterstain was applied.
