NCIt definition : Proto-oncogene c-Fos (380 aa, 41 kDa) is encoded by the human FOS gene. This protein
is involved in transcriptional regulation, DNA binding and signal transduction.;
NCIt note : FOS is involved in growth-related transcriptional control, is a key regulator of osteoclast-macrophage
lineage determination, and is a major component of the heterodimeric DNA-binding AP-1
transcription factor complex, which includes JUN family members. Both proteins contain
a bZIP region. AP-1 binds to TREs (TPA-responsive elements) in the promoters of target
genes. (from OMIM 164810);
