Biological background
Protein function (datasheet): FosB interacts with Jun proteins enhancing their DNA binding activity.
Scientific background (datasheet): FOSB, FBJ murine osteosarcoma viral oncogene homolog B, is a protein that, in humans, is encoded by the FOSB gene. FOSB is a member of Fos gene family which consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. The FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation. The FOSB gene is mapped to 19q13.32. Delta FOSB is a truncated splice variant of FOSB. Delta FosB has been implicated in the development of drug addiction and control of the reward system in the brain, and is linked to changes in a number of other gene products such as CREB and sirtuins. Delta FosB also regulates the commitment of mesenchymal precursor cells to the adipocyte or osteoblast lineage.
Cellular localization (datasheet): Nucleus.
Tissue details (datasheet): Detected in astrocytoma, neuroblastoma and adrenal cortex cell lines. Some isoforms are detected in foreskin fibroblast cell lines, however isoform 17, isoform 18 and isoform 19 are not detected in these cells. .
Sequence similarities (datasheet): Belongs to the bZIP family. Fos subfamily.
Research relevance and current trends
- Commonly studied in contexts related to Angiogenesis,Cancer,Cardiovascular,2339,Epigenetics and Nuclear Signaling,Growth Factors,Growth Factors/Hormones,Neurogenesis,Neurology Process,Neuroscience,Protein Phosphorylation,Receptor Tyrosine Kinases,Signal Transduction,Tyrosine Kinases.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
