General description

Forkhead box O4 (FOXO4 or AFX) is a member of the forkhead family of transcription factors, (FOXO), which play an important role in cellular proliferation, metabolism, stress tolerance, and aging. FOXO transcription factors have a characteristic forkhead domain and are located in the cytoplasm. FOXO4 has similar properties to FOXO1, FOXO3, and FOXO and is associated with acute leukemia. Upon phosphorylation, FOXO4 is translocated from the cytosol to the nucleus. FOXO4 has three phosphorylation sites at Thr32, Ser197, and Ser262. There are 2 pathways, Akt and reversible acetylation, involved in negative control of FOXO4, resulting in cell survival. FOXO4 represses smooth muscle cell (SMC) differentiation by interacting and suppressing myocardin. FOXO4 also down regulates HIF-1 alpha protein levels which prevent hypoxia response.

Specificity

This antibody recognizes FOXO4 at the N-terminus.

Immunogen

Epitope: N-terminus
Synthetic peptide corresponding to the N-terminal region of FOXO4.

Application

Anti-FOXO4 Antibody is an antibody against FOXO4 for use in WB & IC.
Immunocytochemistry:
A 1:500 dilution of this antibody was used to detect FOXO4 in NIH/3T3 and A431 cells. Positive nuclear staining.

Physical form

Affinity purified
Purified rabbit polyclonal antibody precipitated in a solution of 50% saturated ammonium sulfate and PBS containing no preservatives.

Storage and Stability

Stable for 1 year at 2-8ºC from date of receipt.
To reconstitute the antibody, centrifuge the antibody at a moderate speed (5,000 rpm) for 5 minutes. Carefully remove the ammonium sulfate/PBS buffer solution and discard; 10μL of residual ammonium sulfate solution will not affect the re-suspension of the antibody. Do not let the protein pellet dry, as severe loss of antibody reactivity can occur. Re-suspend the antibody pellet in 100L either standard PBS or TBS (pH 7.3-7.5). DO NOT VORTEX. Mix by gentle stirring with a wide pipet tip or gentle finger-tapping. Let the precipitated antibody rehydrate for 1 hour at 4-25°C prior to use. Small particles of precipitated antibody that fail to re-suspend are normal. Vials are overfilled to compensate for any losses.

Analysis Note

Control
Mouse kidney lysate.

The Forkhead Box O (FOXO) transcription factors regulate diverse cellular processes, and in skeletal muscle are both necessary and sufficient for muscle atrophy. Although the regulation of FOXO by Akt is well evidenced in skeletal muscle, the current study demonstrates
