Part of signaling pathways leading to the production of cytokines and interferon. Required for normal antibody isotype switching from IgM to IgG. Plays a role T-cell dependent immune responses. Plays a role in the regulation of antiviral responses. Is an essential constituent of several E3 ubiquitin-protein ligase complexes. May have E3 ubiquitin-protein ligase activity and promote 'Lys-63'-linked ubiquitination of target proteins. Inhibits activation of NF-kappa-B in response to LTBR stimulation. Inhibits TRAF2-mediated activation of NF-kappa-B. Down-regulates proteolytic processing of NFKB2, and thereby inhibits non-canonical activation of NF-kappa-B. Promotes ubiquitination and proteasomal degradation of MAP3K14.\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\u003eStimulate cultured cells with TRAF3 (dose–response + time-course) and collect lysates.\u003c\/li\u003e\n\u003cli\u003eMeasure downstream markers after TRAF3 treatment (WB\/qPCR\/ELISA readouts).\u003c\/li\u003e\n\u003cli\u003eQuantify TRAF3 using standard curves in plate-based assays (assay development).\u003c\/li\u003e\n\u003cli\u003eRun receptor binding kinetics for TRAF3 by SPR\/BLI (in vitro profiling).\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 (Q13114) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/Q13114 - NCBI Gene search (TRAF3) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=TRAF3 - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=TRAF3 - 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":53059253895533,"sku":"CSB-BP024148HU-1MG","price":2710.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059349381485,"sku":"CSB-BP024148HU-100UG","price":1120.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059349414253,"sku":"CSB-BP024148HU-20UG","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-BP024148HU-SDS.jpg?v=1772280060","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-tnf-receptor-associated-factor-3-traf3-bhp10514261","provider":"BioHippo","version":"1.0","type":"link"}
