[[http://www.uniprot.org/uniprot/FOS_MOUSE FOS_MOUSE]] Nuclear phosphoprotein which forms a tight but non-covalently linked complex with the JUN/AP-1 transcription factor. On TGF-beta activation, forms a multimeric SMAD3/SMAD4/JUN/FOS complex, at the AP1/SMAD-binding site to regulate TGF-beta-mediated signaling (By similarity). 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.<ref>PMID:12134156</ref> <ref>PMID:12972619</ref> <ref>PMID:15719069</ref> <ref>PMID:21998197</ref> <ref>PMID:22105363</ref> [[http://www.uniprot.org/uniprot/MAFB_MOUSE MAFB_MOUSE]] Acts as a transcriptional activator or repressor. Plays a pivotal role in regulating lineage-specific hematopoiesis by repressing ETS1-mediated transcription of erythroid-specific genes in myeloid cells. Required for monocytic, macrophage, podocyte and islet beta cell differentiation. Involved in renal tubule survival and F4/80 maturation. Activates the insulin and glucagon promoters. Together with PAX6, transactivates weakly the glucagon gene promoter through the G1 element. SUMO modification controls its transcriptional activity and ability to specify macrophage fate. Binds element G1 on the glucagon promoter. Involved either as an oncogene or as a tumor suppressor, depending on the cell context.<ref>PMID:10790365</ref> <ref>PMID:16443760</ref> <ref>PMID:16847325</ref> <ref>PMID:17901057</ref> <ref>PMID:17548468</ref> <ref>PMID:18199433</ref> <ref>PMID:19143053</ref>
