Biological background
Functionally, RFXANK antibody identifies a 260-amino-acid nuclear protein containing multiple ankyrin repeats that mediate protein-protein interactions within the RFX complex. RFXANK acts as a scaffold for assembling the class II transactivator (CIITA) and other coactivators at MHC class II promoters, enabling antigen-presenting cells to express HLA-D gene products critical for immune recognition.
The RFXANK gene is located on chromosome 19p12 and is highly expressed in antigen-presenting cells such as B lymphocytes, macrophages, and dendritic cells. Its function is indispensable for adaptive immune activation and T-cell mediated responses.
Pathologically, mutations in RFXANK cause bare lymphocyte syndrome type II (BLS II), a severe immunodeficiency characterized by loss of MHC class II expression and defective antigen presentation. Research using RFXANK antibody supports studies in transcriptional regulation, immunodeficiency, and antigen presentation biology.
RFXANK antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect transcriptional regulators involved in immune gene activation.
Structurally, Regulatory factor X-associated ankyrin-containing protein contains tandem ankyrin repeats and a nuclear localization signal that mediate its assembly into DNA-binding complexes. This antibody enables investigation of RFXANK's role in immune gene transcription and MHC regulation.
Research relevance and current trends
- Connecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).
- Considering isoforms and post-translational regulation when interpreting protein-level changes.
- Comparing results across species and model systems with matched controls.
Common research applications
- Western blotting: compare relative abundance and activation-state changes across conditions.
- Immunofluorescence: visualize subcellular distribution and cell-to-cell heterogeneity.
- Flow cytometry: quantify target-positive populations and signal shifts at single-cell resolution.
- ELISA: support antibody-based quantification in assay formats where applicable.
Interpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.
Notes for experimental interpretation
- Signal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.
- Species differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.
Antibody notes: Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.
