Restricts the replication of multiple viruses including flaviviruses or coronaviruses. Together with viperin\/RSAD2 and ddhCTP, suppresses the replication of several coronaviruses through inhibition of the viral RNA-dependent RNA polymerase activities. Concerning flaviviruses, restricts RNA translation when localized to the mitochondria independently of its kinase activity. Is able to phosphorylate dUMP, dCMP, CMP, UMP and monophosphates of the pyrimidine nucleoside analogs ddC, dFdC, araC, BVDU and FdUrd with ATP as phosphate donor. Efficacy is highest for dUMP followed by dCMP while CMP and UMP are poor substrates. Controls therefore mitochondrial DNA synthesis by supplying required deoxyribonucleotides. CMPK2-dependent mitochondrial DNA synthesis is necessary for the production of oxidized mitochondrial DNA fragments after exposure to NLRP3 activators. In turn, cytosolic oxidized mtDNA associates with the NLRP3 inflammasome complex and is required for its activation\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDomain- and isoform-aware assay design to improve biological interpretation across model systems.\u003c\/li\u003e\n\u003cli\u003eQuantitative workflows emphasizing calibration standards, spike-in controls, and cross-lot comparability.\u003c\/li\u003e\n\u003cli\u003eIn vitro binding\/kinetics profiling (SPR\/BLI) to connect biochemical interactions with cellular phenotypes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMeasure CMPK2 enzymatic activity with defined substrates\/cofactors (in vitro assay).\u003c\/li\u003e\n\u003cli\u003eEvaluate inhibitor\/activator effects on CMPK2 activity across a concentration series.\u003c\/li\u003e\n\u003cli\u003eQuantify CMPK2 using calibration standards in plate-based assays (assay development).\u003c\/li\u003e\n\u003cli\u003eProfile binding interactions of CMPK2 by SPR\/BLI (kinetic characterization).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret results in the context of the biological system, assay format, and any known domain\/isoform constraints for the target.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider species- and isoform-specific differences when comparing results across models or homologs.\u003c\/li\u003e\n\u003cli\u003eFor quantitative assays, include appropriate negative controls and matrix-matched spike-in concepts to assess non-specific signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB entry (Q5EBM0) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/Q5EBM0 - NCBI Gene search (CMPK2) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CMPK2 - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CMPK2 - Reactome pathway browser — Reactome: https:\/\/reactome.org\/ - InterPro protein family resource — EMBL-EBI: https:\/\/www.ebi.ac.uk\/interpro\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53059312746861,"sku":"CSB-EP688686HU-1MG","price":2062.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059468558701,"sku":"CSB-EP688686HU-100UG","price":480.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059468591469,"sku":"CSB-EP688686HU-20UG","price":256.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP688686HU-SDS.jpg?v=1772280389","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-ump-cmp-kinase-2-mitochondrial-cmpk2-bhp10516257","provider":"BioHippo","version":"1.0","type":"link"}
