NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA\/p65, RELB, NFKB1\/p105, NFKB1\/p50, REL and NFKB2\/p52 and the heterodimeric p65-p50 complex appears to be most abundant one. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. NF-kappa-B heterodimeric p65-p50 and RelB-p50 complexes are transcriptional activators. The NF-kappa-B p50-p50 homodimer is a transcriptional repressor, but can act as a transcriptional activator when associated with BCL3. NFKB1 appears to have dual functions such as cytoplasmic retention of attached NF-kappa-B proteins by p105 and generation of p50 by a cotranslational processing. The proteasome-mediated process ensures the production of both p50 and p105 and preserves their independent function, although processing of NFKB1\/p105 also appears to occur post-translationally. p50 binds to the kappa-B consensus sequence 5'-GGRNNYYCC-3', located in the enhancer region of genes involved in immune response and acute phase reactions. In a complex with MAP3K8, NFKB1\/p105 represses MAP3K8-induced MAPK signaling; active MAP3K8 is released by proteasome-dependent degradation of NFKB1\/p105. {ECO:0000269|PubMed:15485931}.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e:ELISA\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTarget_protein\u003c\/b\u003e:NFKB1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReactivity\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay type\u003c\/b\u003e:Sandwich\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSensitivity\u003c\/b\u003e:0.09ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDetection range\u003c\/b\u003e:0.19-12ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSample type\u003c\/b\u003e:Serum, plasma or other biological fluids\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecies\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e:2-8ºC\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay time\u003c\/b\u003e:1h 30m\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUniProt accession\u003c\/b\u003e:P19838\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMASS(Da)\u003c\/b\u003e:105356\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGeneID\u003c\/b\u003e:4790\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSynonyms\u003c\/b\u003e:NFKB1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGene names\u003c\/b\u003e:NFKB1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStandard solution\u003c\/b\u003e:24ng\/ml\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48648186232932,"sku":"E7121Hu","price":1025.92,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_2b3d8444-ba57-4d33-84c4-454925a3b099.jpg?v=1782711389","url":"https:\/\/www.genebiosystems.com\/products\/human-nuclear-factor-nf-kappa-b-p105-subunit-nfkb1-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
