Protein c-Fos is a proto-oncogene and transcription factor that plays an important role in cellular function and human disease including cancer. It is encoded in humans by the FOS gene and frequently forms both homodimers and heterodimers.

When c-fos heterodimerizes with the transcription factor c-jun (from the Jun family), they form an AP-1 (Activator Protein-1) complex which binds DNA at specific sites to modulate gene expression.

c-Fos is a part of a bigger Fos family of transcription factors which includes c-Fos, FosB, Fra-1 and Fra-2. It plays an important role in many cellular functions and has been found to be overexpressed in a variety of cancers.
