Target intelligence / Profile preview

Proto-oncogene c-Fos Protein (c-Fos)

Target
c-Fos
Molecular classification
Transcription factor, Proto-oncogene
01

Overview

Proto-oncogene c-Fos protein is a nuclear transcription factor critical for rapid cellular responses to external stimuli through regulation of gene expression. Its ability to form part of the AP‑1 complex underlies roles ranging from normal development/regeneration to cancer progression when dysregulated.

Other names
FOSAP-1 transcription factor subunit c-Fosp62 c-fos
02

Mechanism of action

Inhibition of AP-1 activity or c-Fos expression; modulation of upstream signaling pathways (e.g., MAPK)
