Nuclear phosphoprotein which forms a tight but non-covalently linked complex with the JUN/AP-1 transcription factor. In the heterodimer, FOS and JUN/AP-1 basic regions each seems to interact with symmetrical DNA half sites. On TGF-beta activation, forms a multimeric SMAD3/SMAD4/JUN/FOS complex at the AP1/SMAD-binding site to regulate TGF-beta-mediated signaling. Has a critical function in regulating the development of cells destined to form and maintain the skeleton. It is thought to have an important role in signal transduction, cell proliferation and differentiation. In growing cells, activates phospholipid synthesis, possibly by activating CDS1 and PI4K2A. This activity requires Tyr-dephosphorylation and association with the endoplasmic reticulum.

c-Fos is an immediate-early gene widely used in neuro research for its role as a marker of neuronal activation. It is rapidly expressed in response to various stimuli, making it an excellent indicator of neuronal activity and functional mapping. Researchers use c-Fos to study brain activity patterns, synaptic plasticity and the effects of drugs or other interventions on the central nervous system, making it essential for understanding dynamic changes in brain function.

The c-Fos protein also known as c-Fos is a component of the Fos family of transcription factors which includes FosB Fra-1 and Fra-2. These proteins play a role in regulating gene expression. c-Fos has a molecular weight of about 55 kDa. You usually find c-Fos expressed in various tissues including the brain providing a marker for neuronal activity and is often induced in response to stimuli like stress growth factors and mitogens. In research settings c-Fos staining and c-Fos immunohistochemistry are techniques commonly used to study activation patterns in cells and tissues.
C-Fos acts as part of the Activator Protein-1 (AP-1) complex a group of DNA-binding proteins that regulate gene transcription. This complex forms when c-Fos and Jun proteins dimerize. The AP-1 complex controls several cellular processes such as proliferation differentiation and apoptosis. Due to its participation in these vital processes c-Fos influences cellular responses to external stimuli and can affect how cells behave under stress.
C-Fos significantly contributes to the MAPK/ERK pathway which plays a role in cell growth and differentiation. It partners with Jun proteins to form functional transcription factors within the MAPK signaling cascade. Additionally c-Fos is involved in the JNK signaling pathway linking it to stress responses and apoptosis. These pathways highlight the partnerships between c-Fos and other proteins like ERK and JNK indicating their intertwined roles in cellular signaling networks.
Researchers associate c-Fos with cancer and neurodegenerative diseases. In cancer c-Fos expression correlates with changes in AP-1 activity which can lead to altered cell growth and proliferation potentially contributing to tumor formation. Its involvement in neurodegenerative diseases reveals its role in neuron apoptosis and cellular stress responses. In these scenarios proteins like Bcl-2 also play a part with CDK1 sharing connections in processes that affect cell cycle and apoptosis illustrating c-Fos's broad significance in both normal and pathological conditions.

Section of rat hippocampus stained with ab208942, at a 1/200 dilution, in red and counterstained with rabbit polyclonal antibody to FOX3/NeuN. DAPI reveals nuclei of neurons and glia in blue. The hippocampal neurons stain green for FOX3/NeuN and a few also are expressing c-FOS, and so appear orange. These cells were spontaneously active at the time the animal was sacrificed.
Multiple bands at 50-65kDa in stimulated or treated cell lysates correspond to different forms of the c-Fos proten.

IHC image of c-Fos staining in a section of formalin-fixed paraffin-embedded normal rat placenta performed on a Leica Biosystems BOND® RX instrument. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab208942, 0.5ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

In Western blot, ab208942 was shown to bind specifically to c-Fos. A band was observed at 45-55 kDa in treated wild-type PC-12 cell lysates with no signal observed at this size in FOS knockout cell line ab281615 (knockout cell lysate ab283111). Treatment of NGF has no observable affect on protein expression in this cell line. To generate this image, wild-type and FOS knockout PC-12 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L 800CW and Goat anti-Rabbit IgG H&L 680RD at 1/20000 dilution.
