c-Fos: Products

Cellular oncogene fos (c-Fos) is one of four Fos family proteins that associate with Jun family proteins to form the AP1 transcription factor complex. It is thought to have an important role in signal transduction, cell proliferation and differentiation. Cellular oncogene fos (c-Fos) is constitutively sumoylated by SUMO1, SUMO2 and SUMO3. Within aa 1132, human c-Fos shares 92% aa sequence identity with mouse and rat c-Fos.
