FunctionTranscription factor which acts as a regulator of cell responses to oxidative stress. In the presence of KIRT1, mediates down-regulation of cyclin D1 and up-regulation of CDKN1B levels which are required for cell transition from proliferative growth to quiescence.
Involvement in diseaseDefects in FOXO1 are a cause of rhabdomyosarcoma type 2 (RMS2) [MIM:268220]. It is a form of rhabdomyosarcoma, a highly malignant tumor of striated muscle derived from primitive mesenchimal cells and exhibiting differentiation along rhabdomyoblastic lines. Rhabdomyosarcoma is one of the most frequently occurring soft tissue sarcomas and the most common in children. It occurs in four forms: alveolar, pleomorphic, embryonal and botryoidal rhabdomyosarcomas. Note=Chromosomal aberrations involving FOXO1 are found in rhabdomyosarcoma. Translocation (2;13)(q35;q14) with PAX3; translocation t(1;13)(p36;q14) with PAX7. The resulting protein is a transcriptional activator.
Sequence similaritiesContains 1 fork-head DNA-binding domain.
modificationsPhosphorylated by AKT1; insulin-induced (By similarity). IGF1 rapidly induces phosphorylation of Ser-256, Thr-24, and Ser-319. Phosphorylation of Ser-256 decreases DNA-binding activity and promotes the phosphorylation of Thr-24, and Ser-319, permitting phosphorylation of Ser-322 and Ser-325, probably by CK1, leading to nuclear exclusion and loss of function. Phosphorylation of Ser-329 is independent of IGF1 and leads to reduced function. Phosphorylated upon DNA damage, probably by ATM or ATR.
Cellular localizationCytoplasm. Nucleus. Shuttles between cytoplasm and nucleus.

ab12161 staining FOXO1A (1/200) in mouse E11 cortical cells cultured for 6 days. Secondary antibody Alexa 546 goat anti rabbit IgG 1/1000 was incubated for 2 hours at room temperature. Images were taken using a Zeiss camera under 40X objectives.
ab12161 staining FOXOA1 (1/200) in the cortical plate (CP) and ventricular zone (VZ=CNS germinal zone) of mouse E13 forebrain tissue. E13 mouse embryos were fixed in 4% paraformaldehyde in PB overnight at 4°C then transferred to 30% sucrose in PBS. Brains were frozen in TissueTek and stored at -80°C. Cryostat coronal sections were cut at 12
µm. Sections were blocked in 0.1% triton in PBS containing 10% normal serum. Primary antibodies were incubated on the sections at 4°C overnight. Secondary antibody Alexa 546 goat anti rabbit IgG 1/1000 was incubated for 2 hours at room temperature. Images were taken using a Zeiss camera under 40X objectives.
