Gene Full Name FBJ murine osteosarcoma viral oncogene homolog
Background The Fos gene family consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. These genes encode leucine zipper proteins that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. As such, the FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation. In some cases, expression of the FOS gene has also been associated with apoptotic cell death. [provided by RefSeq, Jul 2008]
Function 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. [UniProt]
PTM Phosphorylated in the C-terminal upon stimulation by nerve growth factor (NGF) and epidermal growth factor (EGF). Phosphorylated, in vitro, by MAPK and RSK1. Phosphorylation on both Ser-362 and Ser-374 by MAPK1/2 and RSK1/2 leads to protein stabilization with phosphorylation on Ser-374 being the major site for protein stabilization on NGF stimulation. Phosphorylation on Ser-362 and Ser-374 primes further phosphorylations on Thr-325 and Thr-331 through promoting docking of MAPK to the DEF domain. Phosphorylation on Thr-232, induced by HA-RAS, activates the transcriptional activity and antagonizes sumoylation. Phosphorylation on Ser-362 by RSK2 in osteoblasts contributes to osteoblast transformation (By similarity).
Constitutively sumoylated with SUMO1, SUMO2 and SUMO3. Desumoylated by SENP2. Sumoylation requires heterodimerization with JUN and is enhanced by mitogen stimulation. Sumoylation inhibits the AP-1 transcriptional activity and is, itself, inhibited by Ras-activated phosphorylation on Thr-232.
In quiescent cells, the small amount of FOS present is phosphorylated at Tyr-10 and Tyr-30 by SRC. This Tyr-phosphorylated form is cytosolic. In growing cells, dephosphorylated by PTPN2. Dephosphorylation leads to the association with endoplasmic reticulum membranes and activation of phospholipid synthesis.

  • ARG10701 anti-c-Fos antibody [2H2] ICC/IF image

    Immunofluorescence: HeLa cells were serum-starved (left) or serum-starved and then treated with 20% fetal bovine serum (FBS) for 2 hours (right). Cells were then stained with ARG10701 anti-c-Fos antibody [2H2] (green) at 1:1000 dilution and costained with ARG52468 anti-Vimentin antibody (red). DAPI (blue) for nuclear staining.

    Serum starvation inhibits c-Fos expression, while treatment with FBS for 2 hours strongly stimulates c-Fos expression which localizes in the nucleus as shown.

  • ARG10701 anti-c-Fos antibody [2H2] IHC-Fr image

    Immunohistochemistry: Frozen section of Rat hippocampus stained with ARG10701 anti-c-Fos antibody [2H2] (red) and costained with ARG10712 anti-FOX3 / NeuN antibody (green). DAPI (blue) reveals nuclei of neurons and glia.

    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.

    Immunohistochemistry: Mouse brain section (45 µM; fixed by transcardial perfusion with 4% paraformaldehyde) stained with ARG10701 anti-c-Fos antibody [2H2] using a standard HRP-DAB (horseradish peroxidase-3,3'-diaminobenzidine) staining technique. Cells expressing c-Fos show dark color in nucleus.

  • ARG10701 anti-c-Fos antibody [2H2] WB image

    Western blot: Top panel: 1) HeLa cells were serum-starved for 36 hours, and 2) Serum-starved HeLa cells were stimulated with 20% FBS (fetal bovine serum) for 2 hours. ARG10701 anti-c-Fos antibody [2H2] recognizes bands in the range of 50-65 kDa, which represent multiple forms of c-Fos. Serum starvation attenuates c-Fos expression, while 20% FBS strongly stimulates c-Fos expression. Bottom panel:  Blot was stripped and stained with a monoclonal antibody (Clone: 1D4) against GAPDH, used as loading control.

Lysates were stained with ARG10701 anti-c-Fos antibody [2H2] (green) at 1:1000 dilution and Rabbit pAb to GAPDH (red) at 1:20000 dilution.
