Biological function summary
Functions of Fos B include regulation of gene expression through forming AP-1 transcription factor complexes with Jun family proteins. These complexes bind to DNA influencing the expression of genes involved in processes such as cell proliferation differentiation and survival. Fos B is structurally similar to other Fos family proteins such as c-Fos which emphasises its role in response to extracellular signals and stress stimuli. Both Fos B and its isoform Delta Fos B have distinct expression patterns suggesting unique functions.
Pathways
Fos B plays a role in the MAPK/ERK signaling pathway which is essential for transmitting extracellular signals to promote diverse cellular responses. Within this pathway interactions with proteins like Jun lead to modulation of gene expression critical for cellular responses to growth factors. Additionally connections to the CREB signaling pathway link Fos B to processes concerning neuronal plasticity and memory further highlighting its participation in important biological functions.
