This gene belongs to the ephrin receptor subfamily of the protein-tyrosine kinase family. Receptors in the EPH subfamily typically have a single kinase domain and an extracellular region containing a Cys-rich domain and 2 fibronectin type III repeats. By somatic cell hybrid analysis and fluorescence in situ hybridization, the EPHA2 gene is mapped to chromosome 1p36.1. EPHA2 was readily detectable in human lens fiber cells using immunoblot and immunohistochemistry. EGFR and EPHA2 mediated HCV entry by regulating CD81 -claudin-1 (CLDN1) coreceptor associations and viral glycoprotein-dependent membrane fusion.\u003c\/p\u003e\n\u003cp\u003eFor curated annotations (gene\/protein naming, domains, isoforms, and pathway links) for EPH RECEPTOR A2, consult primary databases such as UniProt, NCBI Gene, and Ensembl.\u003c\/p\u003e\n\n\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\n\u003cul\u003e\n  \n\u003cli\u003eContext-dependent expression studies: researchers often examine EPH RECEPTOR A2 abundance and localization across perturbations (genetic, pharmacologic, or environmental) to connect phenotype to molecular changes.\u003c\/li\u003e  \u003cli\u003eReagent reproducibility: there is growing emphasis on antibody specificity checks using orthogonal approaches (e.g., genetic perturbation or independent antibodies) and transparent reporting of clone\/lot information.\u003c\/li\u003e  \u003cli\u003eMulti-modal datasets: antibody-based readouts are increasingly combined with transcriptomics and imaging to relate protein-level measurements to cell-state transitions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCommon research applications\u003c\/h2\u003e\n\u003cul\u003e\n  \n\u003cli\u003eWestern blotting (immunoblot) for relative detection of target protein abundance and apparent molecular weight.\u003c\/li\u003e  \u003cli\u003eFACS: commonly used to detect or compare EPH RECEPTOR A2 across experimental conditions (conceptual guidance only).\u003c\/li\u003e  \u003cli\u003eELISA-based detection or quantification in research assays (format- and epitope-dependent).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhen comparing conditions, interpret changes in signal in the context of sample composition, expected localization, and any known isoform complexity for the target.\u003c\/p\u003e\n\n\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\n\u003cul\u003e\n  \n\u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e alternative splicing or post-translational modifications can change epitope accessibility and apparent molecular weight; interpret bands\/signals accordingly.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eCross-reactivity and matrix effects:\u003c\/strong\u003e background binding can vary by sample type, species, and blocking\/detection chemistries; include appropriate negative controls.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eControl concepts:\u003c\/strong\u003e where feasible, use genetic perturbation (KO\/KD\/overexpression), orthogonal assays, or independent antibodies to support specificity claims.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAntibody considerations:\u003c\/strong\u003e Polyclonal reagents may recognize multiple epitopes and can increase sensitivity but may show broader binding profiles, while monoclonal clones provide a single-epitope readout that can improve consistency across experiments.
