Forkhead box O3A (FOXO3A) is a member of the forkhead family of transcription factors (FOXO), which play an important role in cellular proliferation, metabolism, stress tolerance, and aging. FOXO transcription factors have a characteristic forkhead domain and are located in the cytoplasm. Upon oxidative stress, FOXO3A translocates to the nucleus where binding to the DNA sequence 5'-[AG]TAAA[TC]A-3' occurs and IGF-1 is dephosphlorated, resulting in apoptosis. In order for the cell to survive, IGF-1 must be phosphlorated by AKT1/PKB at Thr32 and Ser-253, which will result in retention and inactivation of FOXO3A in the cytoplasm. Translocation of FOXO3A with the MLL gene has been associated with secondary acute leukemia.
