Target
-
Function
Transcriptional 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 specificity
Ubiquitous. -
Involvement in disease
Note=A chromosomal aberration involving FOXO3 is found in secondary acute leukemias. Translocation t(6;11)(q21;q23) with MLL/HRX. -
Sequence similarities
Contains 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 localization
Cytoplasm > cytosol. Nucleus. Translocates to the nucleus upon oxidative stress and in the absence of survival factors. - Information by UniProt

Predicted band size: 71 kDa
Observed band size: 105,67 kDa why is the actual band size different from the predicted?
Serum treatment:-
1. Add fresh basic medium to the vessels and starve the cells for 18-24 hours.
-
2. Drain the cultured medium, add growth medium and basic medium containing 10% serum to the vessels.

Immunocytochemistry/ Immunofluorescence - Anti-FOXO3A (phospho S253) antibody (ab47285)ICC/IF image of ab47285 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab47285, 1µg/ml) overnight at +4°C. 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) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. -

Cells were fixed in formaldehyde, permebilized in 0.5% Triton X-100 and then blocked in 5% BSA for 1 hour at 25°C. The primary antibody was used at 1/200 dilution in PBS and incubated with sample at 4°C for 12 hours. An Alexa Fluor® 488 conjugated Goat polyclonal to rabbit IgG was used as secondary at 1/500 dilution. Image show green staining with ab47285 and blue with DAPI.
