Overview
Anti-NHERF-1/EBP50 Antibody is an antibody targeting Na+/H+ exchange regulatory cofactor 1, Ezrin-radixin-moesin-binding phosphoprotein 50, SLC9A3R1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Na+/H+ exchange regulatory cofactor 1, Ezrin-radixin-moesin-binding phosphoprotein 50, SLC9A3R1 (also reported as Na+/H+ exchange regulatory cofactor 1, Ezrin-radixin-moesin-binding phosphoprotein 50, SLC9A3R1).
- Immunogen/epitope region: Between the PDZ2 and the ERM binding domains..
- Homology note: Mouse - 13/14 amino acid residues identical; human - 12/14 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Mouse.
- Cited use: IFC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
The Na+/H+ exchange regulatory factor (EBP-50 or NHERF-1) is a 55 kD cytoplasmic protein adaptor that recruits a wide variety of cellular proteins.Many of the interacting proteins do so through the two tandem PDZ domains (protein-binding domains conserved in the mammalian synaptic protein PSD-95/DlgA/ZO-1) and the C-terminal ERM (ezrin, radixin, moesin) binding region.NHERF-1 was first identified as an adaptor necessary for the function of the Na+/H+ exchanger isoform 3 (NHE3) in renal apical cells.1 Since then it has been identified in cells of epithelial origin in several tissues such as gastrointestinal and lung.NHERF-1 has been shown to interact with a growing number of proteins including ion channels (ROMK, CFTR, P2Y1, TRPC4 and TRPC6), growth factor receptors (PDGFR), phospholipase C isoforms (PLCb1, PLCb2, PLCb3), non-receptor protein tyrosine kinases (YAP65) and several cytoskeletal proteins that link membrane proteins to the underlying actin cytoskeleton.2Recently, it has been shown that NHERF-1 expression was elevated in breast tumors compared to the expression in adjacent normal tissue.3
Research relevance and current trends
- Comparing target expression across perturbations, genotypes, or treatment conditions.
- Interpreting localization shifts alongside pathway or phenotypic readouts.
- Using orthogonal controls (KO/KD, peptide competition, isotype concepts) to support conclusions.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-PZ006.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
