It is mapped to 13q31.1. This gene encodes a member of the POU-IV class of neural transcription factors. This protein is expressed in a subset of retinal ganglion cells and may be involved in the developing sensory nervous system. This protein may also promote the growth of cervical tumors. A translocation of this gene is associated with some adult acute myeloid leukemias.\u003c\/p\u003e\n\u003cp\u003eFor curated annotations (gene\/protein naming, domains, isoforms, and pathway links) for BRN3A, 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 BRN3A 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\u003eDirect ELISA: commonly used to detect or compare BRN3A across experimental conditions (conceptual guidance only).\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.
