The protein encoded by this gene appears to be multifunctional. Along with PCBP-1 and hnRNPK, it is one of the major cellular poly(rC)-binding proteins. The encoded protein contains three K-homologous (KH) domains which may be involved in RNA binding. Together with PCBP-1, this protein also functions as a translational coactivator of poliovirus RNA via a sequence-specific interaction with stem-loop IV of the IRES, promoting poliovirus RNA replication by binding to its 5'-terminal cloverleaf structure. It has also been implicated in translational control of the 15-lipoxygenase mRNA, human papillomavirus type 16 L2 mRNA, and hepatitis A virus RNA. The encoded protein is also suggested to play a part in formation of a sequence-specific alpha-globin mRNP complex which is associated with alpha-globin mRNA stability. This multiexon structural mRNA is thought to be retrotransposed to generate PCBP-1, an intronless gene with functions similar to that of PCBP2. This gene and PCBP-1 have paralogous genes (PCBP3 and PCBP4) which are thought to have arisen as a result of duplication events of entire genes. This gene also has two processed pseudogenes (PCBP2P1 and PCBP2P2). Multiple transcript variants encoding different isoforms have been found for this gene.\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\u003eImmunofluorescence: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003cli\u003eFlow cytometry: 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 Q15366 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q15366 - Gene search: E2 — NCBI Gene — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=E2 - Ensembl search: E2 — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=E2 - PubMed search: E2 antibody — PubMed — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=E2+antibody - Reactome search: E2 — Reactome — https:\/\/reactome.org\/content\/query?q=E2 --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53046454911341,"sku":"RQ7821","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_bff1d9d7-a0c6-47fb-a4d7-ca3e3f357049.jpg?v=1772000734","url":"https:\/\/www.ebiohippo.com\/products\/hnrnp-e2-antibody-heterogeneous-nuclear-ribonucleoprotein-e2-pcbp2-bha17129384","provider":"BioHippo","version":"1.0","type":"link"}
