CC   -!- FUNCTION: Nuclear phosphoprotein which forms a tight but non-covalently
CC       linked complex with the JUN/AP-1 transcription factor. On TGF-beta
CC       activation, forms a multimeric SMAD3/SMAD4/JUN/FOS complex, at the
CC       AP1/SMAD-binding site to regulate TGF-beta-mediated signaling. Has a
CC       critical function in regulating the development of cells destined to
CC       form and maintain the skeleton. It is thought to have an important role
CC       in signal transduction, cell proliferation and differentiation (By
CC       similarity). In growing cells, activates phospholipid synthesis,
CC       possibly by activating CDS1 and PI4K2A. This activity requires Tyr-
CC       dephosphorylation and association with the endoplasmic reticulum (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Heterodimer; with JUN (By similarity). Component of the
CC       SMAD3/SMAD4/JUN/FOS complex required for synergistic TGF-beta-mediated
CC       transcription at the AP1-binding site (By similarity). Interacts with
CC       SMAD3; the interaction is weak even on TGF-beta activation (By
CC       similarity). Interacts with MAFB (By similarity). Interacts with DSIPI;
CC       this interaction inhibits the binding of active AP1 to its target DNA
CC       (By similarity). Interacts with CDS1 and PI4K2A (By similarity).
CC       Interacts (via bZIP domain and leucine-zipper region) with the
CC       multiprotein chromatin-remodeling complexes SWI/SNF: SWI/SNF-A (BAF)
CC       subunits SMARCB1, SMARCC2 and SMARCD1 (By similarity). Interacts (via
CC       bZIP domain and leucine-zipper region) with ARID1A (By similarity).
CC       {ECO:0000250|UniProtKB:P01100, ECO:0000250|UniProtKB:P01101,
CC       ECO:0000250|UniProtKB:P12841}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00978}.
CC       Endoplasmic reticulum {ECO:0000250}. Cytoplasm, cytosol {ECO:0000250}.
CC       Note=In quiescent cells, present in very small amounts in the cytosol.
CC       Following induction of cell growth, first localizes to the endoplasmic
CC       reticulum and only later to the nucleus. Localization at the
CC       endoplasmic reticulum requires dephosphorylation at Tyr-10 and Tyr-30
CC       (By similarity). {ECO:0000250}.
CC   -!- PTM: Phosphorylated in the C-terminal upon stimulation by nerve growth
CC       factor (NGF) and epidermal growth factor (EGF). Phosphorylated, in
CC       vitro, by MAPK and RSK1. Phosphorylation on both Ser-363 and Ser-375 by
CC       MAPK1/2 and RSK1/2 leads to protein stabilization with phosphorylation
CC       on Ser-375 being the major site for protein stabilization on NGF
CC       stimulation. Phosphorylation on Ser-363 and Ser-375 primes further
CC       phosphorylations on Thr-326 and Thr-332 through promoting docking of
CC       MAPK to the DEF domain. Phosphorylation on Thr-232, induced by HA-RAS,
CC       activates the transcriptional activity and antagonizes sumoylation.
CC       Phosphorylation on Ser-363 by RSK2 in osteoblasts contributes to
CC       osteoblast transformation (By similarity). {ECO:0000250}.
CC   -!- PTM: Constitutively sumoylated with SUMO1, SUMO2 and SUMO3.
CC       Desumoylated by SENP2. Sumoylation requires heterodimerization with JUN
CC       and is enhanced by mitogen stimulation. Sumoylation inhibits the AP-1
CC       transcriptional activity and is, itself, inhibited by Ras-activated
CC       phosphorylation on Thr-232 (By similarity). {ECO:0000250}.
CC   -!- PTM: In quiescent cells, the small amount of FOS present is
CC       phosphorylated at Tyr-10 and Tyr-30 by SRC. This Tyr-phosphorylated
CC       form is cytosolic. In growing cells, dephosphorylated by PTPN2.
CC       Dephosphorylation leads to the association with endoplasmic reticulum
CC       membranes and activation of phospholipid synthesis (By similarity).
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the bZIP family. Fos subfamily. {ECO:0000305}.
