This gene encodes transcription factor 4, a basic helix-loop-helix transcription factor. The encoded protein recognizes an Ephrussi-box ('E-box') binding site ('CANNTG') - a motif first identified in immunoglobulin enhancers. This gene is broadly expressed, and may play an important role in nervous system development. Defects in this gene are a cause of Pitt-Hopkins syndrome. In addition, an intronic CTG repeat normally numbering 10-37 repeat units can expand to \u0026gt;50 repeat units and cause Fuchs endothelial corneal dystrophy. Multiple alternatively spliced transcript variants that encode different proteins have been described.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eComparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).\u003c\/li\u003e \u003cli\u003eSubcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.\u003c\/li\u003e \u003cli\u003eIntegration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003cli\u003eELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eInterpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands\/signals accordingly.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eEpitope context:\u003c\/strong\u003e binding can depend on protein conformation and sample processing; region information in the title\/immunogen can help anticipate what may be detected.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSpecies differences:\u003c\/strong\u003e predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControl concepts:\u003c\/strong\u003e include negative controls (no-primary\/isotype), and where possible genetic controls (KO\/KD) or independent antibodies to strengthen conclusions.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry P15884 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P15884 - Gene search: TCF4 — NCBI Gene — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=TCF4 - Ensembl search: TCF4 — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=TCF4 - PubMed search: TCF4 antibody — PubMed — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=TCF4+antibody - Reactome search: TCF4 — Reactome — https:\/\/reactome.org\/content\/query?q=TCF4 --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53046428631405,"sku":"RQ7105","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a4933947-b368-4da2-af9b-e3c36bfd9fa7.jpg?v=1772000579","url":"https:\/\/www.ebiohippo.com\/products\/tcf4-antibody-transcription-factor-4-bha17128676","provider":"BioHippo","version":"1.0","type":"link"}
