The mammalian Forkhead Box O (FoxO) transcription factors, FoxO1, FoxO3a and FoxO4 are emerging as an important family of proteins that modulate the expression of genes involved in cell cycle regulation, induction of apoptosis, DNA damage repair and response to oxidative stress. Their transcriptional activity is tightly regulated by the action of several regulatory co-factors, and a series of post-translational modifications controlling a shuttling system, that confines them e...
