Biochem/physiol Actions

Forkhead box O3 is a human protein encoded by the FOXO3 gene and is mapped to chromosomal regions 6q21. It belongs to Forkhead box-O (FoxO) family transcriptional factors and is found to be expressed in all human adult tissue. FoxO family controls the expression of many genes that are involved in a variety of cellular processes such as affecting tumorigenesis, metabolism, stem cell maintenance and lifespan. Its plays an important role in cell cycle regulation, apoptosis, oxidative stress and DNA repair. FOXO transcription factors have the ability to repress Cyclin D1 transcription and may alter Cyclin D1 activity. It is also found to be involved in melanogenesis regulation.

Physical form

Forkhead box O (FOXO) transcription factors regulate diverse cellular processes, affecting tumorigenesis, metabolism, stem cell maintenance, and lifespan. We show that FOXO3 transcription regulation mainly proceeds through the most active subset of enhancers. In addition to the general distinction between...

Forkhead box O (Foxo) transcription factors induce muscle atrophy by upregulating the muscle-specific E3 ubiquitin ligases MuRF-1 and atrogin-1/MAFbx, but other than Akt, the upstream regulators of Foxos during muscle atrophy are largely unknown. To examine the involvement of the...

Synaptic activity and the generation of nuclear calcium signals promote neuronal survival through a transcription-dependent process that is not fully understood. Here we show that one mechanism of activity-induced acquired neuroprotection involves the Forkhead transcription factor, FoxO3a, which is known...
