Protein Structure
UniProt Annotation
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'. Participates in post-transcriptional regulation of MYC: following phosphorylation by MAPKAPK5, promotes induction of miR-34b and miR-34c expression, 2 post- transcriptional regulators of MYC that bind to the 3'UTR of MYC transcript and prevent its translation. {ECO:0000269PubMed:10102273, ECO:0000269PubMed:16751106, ECO:0000269PubMed:21329882}.
Subcellular Localization Cytoplasm, cytosol. Nucleus. Note=Translocates to the nucleus upon oxidative stress and in the absence of survival factors.
Disease Associations Note=A chromosomal aberration involving FOXO3 is found in secondary acute leukemias. Translocation t(6;11)(q21;q23) with KMT2A/MLL1.
Tissue Specificity Ubiquitous. {ECO:0000269PubMed:9479491}.
