Eukaryotic initiation factor 4A-II is a protein that in humans is encoded by the EIF4A2 gene. It is mapped to 18p11.2. Eukaryotic initiation factor 4A plays an important role in the binding of mRNA to the 43S preinitiation complex when protein synthesis begins. Two highly homologous forms of functional EIF4A genes, Eif4a1 and Eif4a2, have been isolated in mice; yeast cells also possess 2 EIF4A genes, TIF1 and TIF2. The murine Eif4a and yeast TIF genes appear to belong to a DEAD-box gene family, whose members exhibit extensive amino acid similarity and contain the asp-glu-ala-asp (DEAD) sequence. DEAD-box genes have been identified in species ranging from E-coli to humans. Their function appears to be related to transcriptional\/translational regulation. Functional note: ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome. In the current model of translation initiation, eIF4A unwinds RNA secondary structures in the 5'-UTR of mRNAs which is necessary to allow efficient binding of the small ribosomal subunit, and subsequent scanning for the initiator codon. Reported localization: Nucleus . Accumulates at sites of DNA damage following UV irradiation. Expression\/tissue context: Ubiquitously expressed; with highest levels in corneal endothelium and lowest levels in brain. Isoform D1 is highly expressed in brain and heart. Isoform D2, isoform D3 and isoform D4 are weakly expressed. .\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eDNA\/RNA: Researchers commonly examine how EIF4A2 (Eukaryotic initiation factor 4A-II) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eEpigenetics and Nuclear Signaling: Researchers commonly examine how EIF4A2 (Eukaryotic initiation factor 4A-II) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eTranslation: Researchers commonly examine how EIF4A2 (Eukaryotic initiation factor 4A-II) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: compare relative EIF4A2 (Eukaryotic initiation factor 4A-II) levels across conditions; band patterns may reflect isoforms and processing.\u003c\/li\u003e\n\u003cli\u003eIHC\/IHC-F: assess spatial distribution of EIF4A2 (Eukaryotic initiation factor 4A-II) across tissue regions and cell types using matched controls.\u003c\/li\u003e\n\u003cli\u003eIF\/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation\/permeabilization and epitope accessibility.\u003c\/li\u003e\n\u003cli\u003eFlow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSpecificity notes:\u003c\/strong\u003e No cross reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCross-reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD\/KO samples when available.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt entry for Q14240: https:\/\/www.uniprot.org\/uniprotkb\/Q14240\/entry - PubMed search (EIF4A2): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=EIF4A2 - NCBI Gene search (EIF4A2): https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=EIF4A2 - Antibody validation concepts (NIH): https:\/\/www.nih.gov\/research-training\/rigor-reproducibility --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53066834870637,"sku":"PB9758","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53067129520493,"sku":"PB9758-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53067129553261,"sku":"PB9758-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53067129586029,"sku":"PB9758-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53067129618797,"sku":"PB9758-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53067129651565,"sku":"PB9758-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53067129684333,"sku":"PB9758-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53067129717101,"sku":"PB9758-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53067129749869,"sku":"PB9758-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53067129782637,"sku":"PB9758-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53067129815405,"sku":"PB9758-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53067129848173,"sku":"PB9758-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/blank_ee924622-6073-4bdf-b1e9-22aa83efcb3a.png?v=1772608188","url":"https:\/\/www.ebiohippo.com\/products\/anti-eif4a2-antibody-picoband-bha21000661","provider":"BioHippo","version":"1.0","type":"link"}
