Inhibits viral replication via the integrated stress response (ISR): EIF2S1\/eIF-2-alpha phosphorylation in response to viral infection converts EIF2S1\/eIF-2-alpha in a global protein synthesis inhibitor, resulting to a shutdown of cellular and viral protein synthesis, while concomitantly initiating the preferential translation of ISR-specific mRNAs, such as the transcriptional activator ATF4.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eEnzyme function studies linking activity changes to phenotype across model systems.\u003c\/li\u003e \u003cli\u003eSmall-molecule and cofactor screens using kinetic readouts in purified systems.\u003c\/li\u003e \u003cli\u003eIntegration of enzymatic readouts with omics data to map pathway-level regulation.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eUse as a reagent for consistent dosing across in vitro assays\u003c\/li\u003e \u003cli\u003eGenerate standard curves or spike-in controls in buffer or sample matrix for plate assays\u003c\/li\u003e \u003cli\u003eStimulate cultured cells with EIF2AK2 (dose–response\/time-course) and track pathway markers\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eConsider isoforms, processing, or post-translational modifications that may differ from endogenous protein across systems.\u003c\/li\u003e \u003cli\u003eFor tagged or labeled formats, confirm that the tag does not occlude binding sites relevant to your readout.\u003c\/li\u003e \u003cli\u003eUse appropriate negative\/positive controls and orthogonal assays when interpreting binding or activity differences.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt Knowledgebase (UniProt): https:\/\/www.uniprot.org\/ - NCBI Gene (NIH\/NCBI): https:\/\/www.ncbi.nlm.nih.gov\/gene\/ - NCBI Protein (NIH\/NCBI): https:\/\/www.ncbi.nlm.nih.gov\/protein\/ - Reactome Pathway Database: https:\/\/reactome.org\/ - KEGG Pathway Database: https:\/\/www.kegg.jp\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53059859284333,"sku":"CSB-YP007511HU1-1MG","price":2010.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059928129901,"sku":"CSB-YP007511HU1-100UG","price":470.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059928162669,"sku":"CSB-YP007511HU1-20UG","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-YP007511HU1-SDS.jpg?v=1772294652","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-interferon-induced-double-stranded-rna-activated-protein-kinase-eif2ak2-partial-bhp10517114","provider":"BioHippo","version":"1.0","type":"link"}
