NCIt synonyms : Forkhead Box Transcription Factor Class O; Fork Head Box Transcription Factor Class O; FoxO;
NCIt definition : A subfamily within the forkhead box (FOX) protein family, which is a family of transcription
factors that contain a forkhead DNA-binding domain. FOXO proteins regulate apoptosis,
cell-cycle progression, oxidative-stress resistance, and tumor suppression. The transcriptional
promoter activity of these factors is regulated by post-translational modifications,
such as phosphorylation, acetylation, and monoubiquitination.;
NCIt note : There are four known members of the FOXO family expressed in humans. They are FOXO1,
FOXO3, FOXO4 and FOXO6.;
