Activity summary

The c-Fos protein also known as c-Fos is a component of the Fos family of transcription factors which includes FosB Fra-1 and Fra-2. These proteins play a role in regulating gene expression. c-Fos has a molecular weight of about 55 kDa. You usually find c-Fos expressed in various tissues including the brain providing a marker for neuronal activity and is often induced in response to stimuli like stress growth factors and mitogens. In research settings c-Fos staining and c-Fos immunohistochemistry are techniques commonly used to study activation patterns in cells and tissues.

Biological function summary

C-Fos acts as part of the Activator Protein-1 (AP-1) complex a group of DNA-binding proteins that regulate gene transcription. This complex forms when c-Fos and Jun proteins dimerize. The AP-1 complex controls several cellular processes such as proliferation differentiation and apoptosis. Due to its participation in these vital processes c-Fos influences cellular responses to external stimuli and can affect how cells behave under stress.

Pathways

C-Fos significantly contributes to the MAPK/ERK pathway which plays a role in cell growth and differentiation. It partners with Jun proteins to form functional transcription factors within the MAPK signaling cascade. Additionally c-Fos is involved in the JNK signaling pathway linking it to stress responses and apoptosis. These pathways highlight the partnerships between c-Fos and other proteins like ERK and JNK indicating their intertwined roles in cellular signaling networks.

Associated diseases and disorders

Researchers associate c-Fos with cancer and neurodegenerative diseases. In cancer c-Fos expression correlates with changes in AP-1 activity which can lead to altered cell growth and proliferation potentially contributing to tumor formation. Its involvement in neurodegenerative diseases reveals its role in neuron apoptosis and cellular stress responses. In these scenarios proteins like Bcl-2 also play a part with CDK1 sharing connections in processes that affect cell cycle and apoptosis illustrating c-Fos's broad significance in both normal and pathological conditions.
