Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HeLa (Human epithelial cells from cervix adenocarcinoma) cells, untreated or treated with 12-o-tetradecanoyl phorbol 13-acetate (TPA) (200nM) for 4h, labeling Fos B with ab184938 at 1/500 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green).

Confocal image showing nuclear staining on HeLa cells. The expression was increaed after treatment with 12-o-tetradecanoyl phorbol 13-acetate (TPA) (200nM) for 4h.

The nuclear counter stain is DAPI (blue). Tubulin is detected with ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution and ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution (red).

The negative controls are as follows :
-ve control 1 : ab184938 at 1/1000 dilution followed by ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution.
-ve control 2 : ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution followed by ab150077 (Alexa Fluor®488 Goat Anti-Rabbit IgG H&L) at 1/500 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab184938).

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

Fos B also known as FosB is a protein encoded by the FOSB gene and belongs to the Fos family of transcription factors. Weighing approximately 46 kDa this protein acts within the cell nucleus and is expressed in several tissues particularly in brain regions. Delta Fos B an isoform of Fos B has gained attention for its stable accumulation in certain neuronal populations. Researchers often study Fos B using techniques like ELISA and immunohistochemistry to investigate its presence and distribution.
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.

Involvement of Fos B has been noted in neurological conditions such as addiction and depression. Delta Fos B in particular accumulates in response to chronic drug exposure and serves as a molecular switch in addiction-related neuroadaptations. Connections with proteins such as CREB and other transcriptional regulators have broadened the understanding of how Fos B and its isoforms impact neural circuits and contribute to the pathology of mood disorders.

Target data

Heterodimerizes with proteins of the JUN family to form an AP-1 transcription factor complex, thereby enhancing their DNA binding activity to gene promoters containing an AP-1 consensus sequence 5'-TGA[GC]TCA-3' and enhancing their transcriptional activity (PubMed : 12618758, PubMed : 28981703). As part of the AP-1 complex, facilitates enhancer selection together with cell-type-specific transcription factors by collaboratively binding to nucleosomal enhancers and recruiting the SWI/SNF (BAF) chromatin remodeling complex to establish accessible chromatin (By similarity). Together with JUN, plays a role in activation-induced cell death of T cells by binding to the AP-1 promoter site of FASLG/CD95L, and inducing its transcription in response to activation of the TCR/CD3 signaling pathway (PubMed : 12618758). Exhibits transactivation activity in vitro (By similarity). Involved in the display of nurturing behavior towards newborns (By similarity). May play a role in neurogenesis in the hippocampus and in learning and memory-related tasks by regulating the expression of various genes involved in neurogenesis, depression and epilepsy (By similarity). Implicated in behavioral responses related to morphine reward and spatial memory (By similarity).. Isoform 11. Exhibits lower transactivation activity than isoform 1 in vitro (By similarity). The heterodimer with JUN does not display any transcriptional activity, and may thereby act as an transcriptional inhibitor (By similarity). May be involved in the regulation of neurogenesis in the hippocampus (By similarity). May play a role in synaptic modifications in nucleus accumbens medium spiny neurons and thereby play a role in adaptive and pathological reward-dependent learning, including maladaptive responses involved in drug addiction (By similarity). Seems to be more stably expressed with a half-life of ~9.5 hours in cell culture as compared to 1.5 hours half-life of isoform 1 (By similarity).
