PCDH11Y is a paralog of PCDH11X, located on the X chromosome, and belongs to the cadherin superfamily. Both genes encode proteins with seven cadherin repeats, a transmembrane domain, and a cytoplasmic tail .
The protein facilitates calcium-dependent cell-cell adhesion, essential for neural circuit organization. Retinoic acid, a developmental signaling molecule, stimulates PCDH11Y activity while suppressing PCDH11X, contributing to sex-specific brain differences .
Evolutionarily, PCDH11Y emerged ~3 million years ago when PCDH11X transposed to the Y chromosome, coinciding with human brain expansion and tool use .
A 2018 study in Proceedings of the National Academy of Sciences investigated whether maternal antibodies to PCDH11Y or NLGN4Y correlate with male sexual orientation . Key findings:
Antibody Assays: Researchers tested plasma from 54 mothers of gay sons (23 with older brothers) and 72 controls using ELISAs for PCDH11Y and NLGN4Y isoforms.
Results:
| Group | Anti-PCDH11Y (Mean ± SD) | Anti-NLGN4Y (Mean ± SD) |
|---|---|---|
| Mothers of gay sons | 0.45 ± 0.12 | 1.20 ± 0.35 |
| Mothers of heterosexual | 0.42 ± 0.10 | 0.85 ± 0.25 |

PCDH11Y (Protocadherin 11 Y-Linked) is a Y-chromosome encoded member of the protocadherin gene family, a subfamily of the cadherin superfamily. The protein consists of an extracellular domain containing 7 cadherin repeats, a transmembrane domain, and a cytoplasmic tail that differs structurally from those of classical cadherins . It plays a fundamental role in calcium-dependent cell-cell adhesion and recognition, which is essential for the segmental development and function of the central nervous system .
Its importance in neurological research stems from its predominant expression in adult and fetal brain tissues, where it contributes to neural development and function . Notably, variations in PCDH11Y genes have been linked to increased risk of neurological disorders, including late-onset Alzheimer's disease, making it a critical target for researchers investigating neuropathological conditions .
PCDH11X and PCDH11Y antibodies target related but distinct proteins encoded by genes located in homologous regions on the X and Y chromosomes, respectively. While both proteins function in cell-cell adhesion and neural development, they differ slightly in structure:
| Feature | PCDH11X | PCDH11Y |
|---|---|---|
| Protein length | 1,347 amino acids | 1,340 amino acids |
| Chromosomal location | X chromosome | Y chromosome |
| Structure | Single-pass type I membrane protein with 7 cadherin domains | Single-pass type I membrane protein with 7 cadherin domains |
| Expression | Adult and fetal brain tissues | Adult and fetal brain tissues |
When selecting antibodies, researchers should consider whether they need specificity to PCDH11Y alone or cross-reactivity with both PCDH11X and PCDH11Y (as with the PCDH11X/Y antibody) . For gender-specific studies, Y-linked isoform-specific antibodies are essential for accurate results .
PCDH11Y antibodies can be utilized across multiple experimental techniques and applications in neuroscience and molecular biology research. Based on the technical specifications from various manufacturers, these antibodies are validated for:
Western Blotting (WB): For protein detection and quantification (typically used at dilutions of 1:500-1:2000)
Enzyme-Linked Immunosorbent Assay (ELISA): For protein quantification in solution
Immunohistochemistry (IHC): For tissue-level expression analysis
Immunoprecipitation (IP): For protein complex isolation and purification
The selection of application should be guided by your specific experimental question, with consideration of the validated applications for your specific antibody clone or preparation .
The choice between monoclonal and polyclonal PCDH11Y antibodies depends on your experimental goals, required specificity, and application context:
Monoclonal Antibodies (e.g., clone 7D12 or 1G5):
Advantages: Higher specificity, reduced batch-to-batch variation, excellent for distinguishing between closely related isoforms
Applications: Ideal for experiments requiring precise epitope recognition, such as detecting specific domains or phosphorylation sites
Example specifications: Mouse monoclonal antibodies like clone 7D12 target specific regions (e.g., AA 57-165) with high reproducibility
Polyclonal Antibodies:
Advantages: Recognize multiple epitopes, potentially higher sensitivity, better for detecting denatured proteins
Applications: Preferred for initial protein detection, proteins expressed at low levels, or when protein conformation may vary
Example specifications: Rabbit polyclonal antibodies targeting regions such as AA 1066-1095 from the C-terminal region
For studies requiring discrimination between PCDH11X and PCDH11Y, monoclonal antibodies with validated specificity for unique epitopes are recommended to minimize cross-reactivity concerns .
Before incorporating a PCDH11Y antibody into critical experiments, comprehensive validation is essential to ensure specificity, sensitivity, and reproducibility:
Positive and negative control samples:
Positive controls: Human brain tissue (adult or fetal) where PCDH11Y is known to be expressed
Negative controls: Tissues without PCDH11Y expression or Y-chromosome (female tissues for Y-linked studies)
Western blot validation:
Knockdown/knockout verification:
Compare antibody signal in wild-type versus PCDH11Y-silenced samples
siRNA or CRISPR-mediated gene silencing provides powerful validation
Peptide blocking:
Cross-reactivity assessment:
Test against PCDH11X to evaluate potential cross-reactivity
Particularly important when studying Y-specific effects
Thorough validation not only verifies antibody performance but also helps establish optimal working dilutions and conditions for each application in your specific experimental system.
PCDH11Y antibodies target different regions of the protein, which impacts their utility for various applications and research questions:
The epitope location is crucial when studying:
Protein-protein interactions: C-terminal antibodies may disrupt or detect cytoplasmic binding partners
Receptor function: N-terminal antibodies may affect cadherin domain interactions
Processing events: Antibodies recognizing different regions may detect distinct cleavage products
For studies requiring detection of alternatively spliced isoforms, selecting antibodies targeting regions common to all variants or specific to particular isoforms is essential for accurate interpretation of results .
Successful PCDH11Y antibody applications require careful attention to sample preparation techniques tailored to both the sample type and detection method:
For Western Blotting:
Lysis buffer composition: Use RIPA buffer supplemented with protease inhibitors to prevent degradation
Sample handling: Maintain samples at 4°C during preparation to preserve protein integrity
Protein denaturation: Heat samples at 95°C for 5 minutes in sample buffer containing SDS and β-mercaptoethanol
Loading: 20-50 μg of total protein per lane is typically sufficient for detection
For Immunofluorescence:
Fixation: 4% paraformaldehyde (15-20 minutes) preserves protein localization
Permeabilization: 0.1-0.2% Triton X-100 for 10 minutes allows antibody access to intracellular epitopes
Blocking: 1-2 hours with 5% normal serum from the same species as the secondary antibody
Antibody dilution: Typically 1:100-1:500 in blocking buffer, incubated overnight at 4°C
For Brain Tissue Preparation:
Fresh tissue: Snap freeze in liquid nitrogen immediately after collection
Fixed tissue: Perfusion with 4% paraformaldehyde followed by sucrose cryoprotection
Antigen retrieval: May be necessary for formalin-fixed tissues; citrate buffer (pH 6.0) at 95°C for 20 minutes
When working with membrane proteins like PCDH11Y, avoid harsh detergents that may disrupt the transmembrane domains, which could affect epitope accessibility and antibody binding .
