It is mapped to 19q13.42. U2 auxiliary factor (U2AF), comprised of a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes the U2AF large subunit which contains a sequence-specific RNA-binding region with 3 RNA recognition motifs and an Arg\/Ser-rich domain necessary for splicing. The large subunit binds to the polypyrimidine tract of introns early during spliceosome assembly. Multiple transcript variants have been detected for this gene, but the full-length natures of only two have been determined to date.\u003c\/p\u003e\n\u003cp\u003eFor curated annotations (gene\/protein naming, domains, isoforms, and pathway links) for U2AF65, 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 U2AF65 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\u003eImmunohistochemistry for spatial mapping of target expression across tissues and cell types.\u003c\/li\u003e  \u003cli\u003eImmunofluorescence for subcellular localization and cell-type specific expression patterns.\u003c\/li\u003e  \u003cli\u003eFACS: commonly used to detect or compare U2AF65 across experimental conditions (conceptual guidance only).\u003c\/li\u003e  \u003cli\u003eDirect ELISA: commonly used to detect or compare U2AF65 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.
