Overview

Description

The forkhead family of transcription factors is home to this gene, which boasts a unique forkhead domain. Researchers have not yet determined the specific function of this gene, but there are indications that it could be involved in promoting muscle growth and differentiation.

Other names

FKH 1, also known as FKH1 or FKHR, is a homolog of Forkhead (Drosophila) protein 1, which is associated with rhabdomyosarcoma. It is a transcription factor known as Forkhead box protein O1 (FoxO1) or Forkhead box protein O1A. This protein, also referred to as Forkhead in rhabdomyosarcoma or Forkhead, Drosophila, homolog of, in rhabdomyosarcoma, plays a crucial role in regulating gene expression. It is encoded by the FOXO1A gene (also known as FOXO1_HUMAN or OTTHUMP00000018301).

Target

Background

This transcription factor plays a crucial role in metabolic homeostasis and is the primary target of insulin signaling. It responds to oxidative stress and regulates redox balance, osteoblast numbers, and bone mass. The factor orchestrates the endocrine function of the skeleton, controlling glucose metabolism, and acts with ATF4 to suppress osteocalcin/BGLAP activity, triggering glucose intolerance and insulin insensitivity. Moreover, it promotes gluconeogenesis in hepatocytes and regulates cell death downstream of CDK1, PKB/AKT1, and SKT4/MST1, including neural cell death. It also mediates insulin action on adipose tissue, regulating the expression of adipogenic genes, adipocyte size, and adipose tissue-specific gene expression. In beta-cells, the factor controls the transcriptional activity of GADD45A and the repair of nitric oxide-damaged DNA. Finally, it is required for the autophagic cell death induction in response to starvation or oxidative stress.

Tissue specificity

Ubiquitous.

Posttranslational modificationPhosphorylation by NLK promotes nuclear export and inhibits the transcriptional activity. In response to growth factors, phosphorylation on Thr-24, Ser-256 and Ser-322 by PKB/AKT1 promotes nuclear export and inactivation of transactivational activity. Phosphorylation on Thr-24 is required for binding 14-3-3 proteins. Phosphorylation of Ser-256 decreases DNA-binding activity and promotes the phosphorylation of Thr-24 and Ser-319, permitting phosphorylation of Ser-322 and Ser-325, probably by CDK1, leading to nuclear exclusion and loss of function. Stress signals, such as response to oxygen or nitric oxide, attenuate the PKB/AKT1-mediated phosphorylation leading to nuclear retention. Phosphorylation of Ser-329 is independent of IGF1 and leads to reduced function. Dephosphorylated on Thr-24 and Ser-256 by PP2A in beta-cells under oxidative stress leading to nuclear retention (By similarity). Phosphorylation of Ser-249 by CDK1 disrupts binding of 14-3-3 proteins leading to nuclear accumulation and has no effect on DNA-binding nor transcriptional activity. Phosphorylation by STK4/MST1 on Ser-212, upon oxidative stress, inhibits binding to 14-3-3 proteins and nuclear export.Acetylated. Acetylation at Lys-262, Lys-265 and Lys-274 are necessary for autophagic cell death induction. Deacetylated by SIRT2 in response to oxidative stress or serum deprivation, thereby negatively regulating FOXO1-mediated autophagic cell death.Ubiquitinated by SRT2. Ubiquitination leads to proteasomal degradation.Methylation inhibits AKT1-mediated phosphorylation at Ser-256 and is increased by oxidative stress.Once in the nucleus, acetylated by CREBBP/EP300. Acetylation diminishes the interaction with target DNA and attenuates the transcriptional activity. It increases the phosphorylation at Ser-256. Deacetylation by SIRT1 results in reactivation of the transcriptional activity. Oxidative stress by hydrogen peroxide treatment appears to promote deacetylation and uncoupling of insulin-induced phosphorylation. By contrast, resveratrol acts independently of acetylation.
