Biological background
Protein function (datasheet): Specifically binds to the upstream regulatory region of type I IFN and IFN-inducible MHC class I genes (the interferon consensus sequence (ICS)). Plays a negative regulatory role in cells of the immune system. Involved in CD8 (+) dendritic cell differentiation by forming a complex with the BATF-JUNB heterodimer in immune cells, leading to recognition of AICE sequence (5'-TGAnTCA/GAAA-3'), an immune-specific regulatory element, followed by cooperative binding of BATF and IRF8 and activation of genes (By similarity). .
Scientific background (datasheet): Interferon regulatory factor 8 (IRF8) also known as Interferon consensus sequence-binding protein (ICSBP), is a protein that in humans is encoded by the IRF8 gene. By genomic sequence analysis, the IRF8 gene is mapped to chromosome 16q24.1. Interferon consensus sequence-binding protein (ICSBP) is a transcription factor of the interferon (IFN) regulatory factor (IRF) family. The IRF family proteins bind to the IFN-stimulated response element (ISRE) and regulate expression of genes stimulated by type I IFNs, namely IFN-alpha and IFN-beta. IRF family proteins also control expression of IFN-alpha and IFN-beta-regulated genes that are induced by viral infection. IRF8 is a transcription factor that plays critical roles in the regulation of lineage commitment and in myeloid cell maturation including the decision for a common myeloid progenitor (CMP) to differentiate into a monocyte precursor cell.
Cellular localization (datasheet): Nucleus .
Tissue details (datasheet): Predominantly expressed in lymphoid tissues. .
Sequence similarities (datasheet): Belongs to the IRF family.
Research relevance and current trends
- Commonly studied in contexts related to Epigenetics and Nuclear Signaling,Immunology,Innate Immunity,TLR Signaling,Transcription.
- 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.
- Immunofluorescence / ICC: Visualize subcellular localization and co-localization patterns; consider fixation/permeabilization compatibility and controls.
- 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.
