Enables DNA-binding transcription factor activity; sequence-specific DNA binding activity; and transcription coactivator binding activity. Involved in several processes, including cellular response to dexamethasone stimulus; enamel mineralization; and regulation of transcription, DNA-templated. Located in cytosol and nucleus. Used to study non-alcoholic fatty liver disease. Human ortholog(s) of this gene implicated in alveolar rhabdomyosarcoma. Orthologous to human FOXO1 (forkhead box O1).
