This gene is mapped to 5p13.3. The transcriptional cofactor PC4 is an ancient single-strand DNA (ssDNA)-binding protein that has a homologue in bacteriophage T5 where it is likely the elusive replicative ssDNA-binding protein. The recombinant PC4 is shown to function identically to the native protein through its interaction with TAFs.\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\u003eImmunohistochemistry: 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 P53999 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P53999 - Gene search: SUB1 — NCBI Gene — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=SUB1 - Ensembl search: SUB1 — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=SUB1 - PubMed search: SUB1 antibody — PubMed — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=SUB1+antibody - Reactome search: SUB1 — Reactome — https:\/\/reactome.org\/content\/query?q=SUB1 --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53046426435949,"sku":"RQ7040","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_e77e0c6a-3c7a-433f-bf12-03791583219b.jpg?v=1772000567","url":"https:\/\/www.ebiohippo.com\/products\/sub1-antibody-positive-cofactor-4-pc4-bha17128611","provider":"BioHippo","version":"1.0","type":"link"}
