DCAF6 Antibody

What is DCAF6 and why is it important to study?

DCAF6, also known as Nuclear Receptor Interaction Protein (NRIP) or IQ motif and WD repeat-containing protein 1 (IQWD1), is an 860 amino acid protein that localizes to the nucleus and contains one IQ domain and seven WD-repeats . This protein functions as a ligand-dependent coactivator of nuclear receptors and specifically enhances the transcriptional activity of androgen receptor (AR) and glucocorticoid receptor (GR) . DCAF6 is expressed in testis, skeletal muscle, prostate, and heart .

Its importance stems from its role in hormone signaling pathways, particularly in androgen receptor signaling, which has implications for prostate cancer research and other hormone-dependent conditions. Northern Blot analysis has detected high expression of NRIP in skeletal muscle and testis with lower expression in heart, prostate, and adrenal gland .

What are the key characteristics of commercially available DCAF6 antibodies?

Currently available DCAF6 antibodies exhibit several common characteristics:

Most DCAF6 antibodies require validation for specific applications and cell/tissue types of interest.

What is the most appropriate application method for DCAF6 antibody detection?

The choice of application method depends on your research question:

• Immunohistochemistry (IHC): Optimal for localizing DCAF6 in tissue sections. Verified samples include human colon cancer and human brain tissues . Typical dilutions range from 1:50-1:200 .

• Western Blotting (WB): Effective for determining protein expression levels and molecular weight. Several antibodies are specifically validated for this purpose .

• Immunofluorescence (IF): Ideal for subcellular localization studies, confirming nuclear localization of DCAF6 .

• ELISA: Useful for quantitative detection, with recommended dilutions ranging from 1:2000-1:5000 .

• Immunoprecipitation (IP): Valuable for studying protein-protein interactions, particularly for investigating DCAF6's interaction with nuclear receptors .

The nuclear localization of DCAF6 makes nuclear isolation and proper fixation particularly important in all protocols .

How should DCAF6 antibodies be stored and handled to maintain activity?

For optimal stability and activity:

• Store antibodies at -20°C to -80°C for long-term storage .

• Avoid repeated freeze-thaw cycles which can cause protein denaturation and loss of activity .

• Most DCAF6 antibodies are supplied in glycerol-containing buffers (typically 40-50% glycerol) to prevent freeze damage .

• When shipped with ice packs, immediately store antibodies at the recommended temperature upon receipt .

• Working dilutions can be prepared and stored at 4°C for short periods (1-2 weeks), but should be aliquoted and frozen for longer storage .

• Some products have validated stability of 12 months when properly stored .

How can I validate DCAF6 antibody specificity for my experimental system?

Rigorous validation is critical due to potential specificity issues with antibodies:

• Knockout/Knockdown Controls: The gold standard for validation. Test the antibody in DCAF6 knockout or knockdown cell lines to confirm signal absence/reduction .

• Multiple Antibody Approach: Use at least two different antibodies targeting different epitopes of DCAF6 and compare their staining/banding patterns .

• Peptide Competition Assay: Pre-incubate the antibody with the immunizing peptide to confirm signal blockage.

• Cross-Species Reactivity Testing: If your antibody is claimed to work across species, validate in each species separately .

• Recombinant Protein Controls: Use recombinant DCAF6 proteins as positive controls in your assays .

As noted in recent reproducibility initiatives like YCharOS (Antibody Characterization through Open Science), standardized characterization processes involving knockout cell lines have become critical for evaluating antibody specificity .

What are the optimal conditions for detecting DCAF6 in co-immunoprecipitation experiments studying nuclear receptor interactions?

When studying DCAF6 interactions with nuclear receptors like AR:

• Nuclear Extraction Optimization:

  • Use specialized nuclear extraction buffers containing DNase/RNase to disrupt chromatin associations

  • Include phosphatase inhibitors to preserve phosphorylation states that may be critical for interactions

• Co-IP Protocol Refinements:

  • Use mild detergents (0.1-0.3% NP-40 or Triton X-100) to preserve protein complexes

  • Consider crosslinking with formaldehyde (0.1-0.3%) to stabilize transient interactions

  • Rotate samples at 4°C overnight for complete antibody binding

• Buffer Considerations:

  • Include 10-20 mM sodium molybdate to stabilize steroid receptor complexes

  • Add protease inhibitors to prevent degradation during long incubations

• Antibody Selection:

  • For DCAF6-AR interaction studies, affinity-captured western blot approaches have been successfully employed

  • Consider whether to IP with anti-DCAF6 or anti-AR antibody based on relative abundance in your system

• Controls:

  • Include hormone-treated versus untreated samples (DCAF6 functions as a ligand-dependent coactivator)

  • Use IgG controls matched to your primary antibody species

This approach has successfully identified DCAF6-AR interactions in previous studies .

What are the main challenges in antibody-based detection of DCAF6 isoforms and how can they be addressed?

DCAF6 exists in three isoforms produced by alternative splicing events , creating specific detection challenges:

• Isoform-Specific Detection Challenges:

  • Commercially available antibodies may not distinguish between the three DCAF6 isoforms

  • Isoforms may have different subcellular distributions or tissue expression patterns

• Methodological Solutions:

  • Consider generating isoform-specific knockouts or overexpression systems

  • Perform phosphatase treatments to eliminate post-translational modifications that may complicate isoform identification

• Interpretation Guidelines:

  • Document the exact epitope region of your antibody (e.g., AA 1-513, AA 300-350)

  • Consider how this region relates to known isoform differences

  • Be cautious about attributing function to "DCAF6" without isoform specification

How can structural insights into antibody-antigen recognition improve DCAF6 antibody design and application?

Understanding the structural basis of antibody-antigen recognition can significantly enhance DCAF6 antibody applications:

• Complementarity Determining Regions (CDRs) and Epitope Recognition:

  • While the six hypervariable loops (CDRs) within antibody variable domains are traditionally considered responsible for antigen recognition, recent structural analyses suggest this is an oversimplification
