    basic FUNCTION
  • putative gene regulator for cellular mechanism mediating neuronal excitability and survival
  • having tumour-suppressing and proapoptotic function in various cancer types
  • may undergo cell cycle dependent phosphorylation, in which some kinases including AURKA play a role in catalyzing the post translational modification of FOS
  • is able to regulate MZB cell development even in the absence of NOTCH2 5)
  • enhanced cytokine production and effector function of T cells may promote antitumor immunity when FOS fails to up-regulate PDCD1 during tumor progression
  • T-cell FOS subsequently induces PDCD1 expression in response to tumor progression
  • T-cell FOS expression promotes tumor growth following inoculation with tumor cells
  • suppresses antitumor T-cell function
  • FOS and RPS6 are induced by the biochemical activation of neurons, and therefore, these markers may be most responsive to stimuli that modulate neurons such as neuro-peptides and biogenic amines
  • critical cAMP effector, able to regulate the re-expression and splicing of epigenetically silenced genes associated with maturation (CD44) in retinoid-resistant NB4-LR1 leukemia cells
  • CELLULAR PROCESS cell life, proliferation/growth
    nucleotide, transcription
    PHYSIOLOGICAL PROCESS circadian , nervous system
    signaling signal transduction
    a component
  • forming heterodimers, the AP-1 complex with JUN family of proteins
    DNA binding to the AP1 sequence of many genes
    small molecule
  • interacting wwwith NR5A1, NR5A2 that are expressed in endometrial cancer
  • interacting with AURKA (Aurora-A is engaged in the regulation of FOS protein-protein interaction)
  • forms AP-1 transcription complexes with heterodimerization partners such as c-Jun, JunB, and JunD
  • bind to the promoters of a multitude of genes involved in critical cellular responses such as cell growth and proliferation, cell cycle regulation, embryonic development and cancer
  • interacting with KDM2B (KDM2B is an important anti-apoptotic molecule, which directly binds and represses FOS promoter in order for cancer cells to resist TRAIL-induced apoptosis)
  • NOTCH2 directly controls FOS transcription associated with Marginal zone B (MZB) cells development 5)
  • clear interaction between NOTCH2 and FOS, but the exact role of FOS in forming MZB cells has yet to be determined 5)
  • synthesis of FN1 is mediated by a transcriptional complex consisting of NFATC1, SP7 and FOS
  • dynamic interaction of SNAPC1 with elongating POLR2A during activation of the FOS gene by EGF
  • AFF2 is an upstream regulator of FOS and JUN, and further link deregulation of the immediate early response genes to the pathology of intellectual disability (ID)- and FRAXE-associated ID in particular
  • CARM1 represses replicative senescence by methylating ELAVL1 and thereby enhancing ELAVL1 ability to regulate the turnover of CCNA1, CCNB1, FOS, SIRT1, and CDKN2A mRNAs (
  • activation of the MAPK7/MAP2K5 pathway with CSF1R is required for osteoclast differentiation, which may induce differentiation through the induction of FOS
