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. 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. In a non-canonical activation pathway, the MAP3K14-activated CHUK\/IKKA homodimer phosphorylates NFKB2\/p100 associated with RelB, inducing its proteolytic processing to NFKB2\/p52 and the formation of NF-kappa-B RelB-p52 complexes. The NF-kappa-B heterodimeric RelB-p52 complex is a transcriptional activator. The NF-kappa-B p52-p52 homodimer is a transcriptional repressor. NFKB2 appears to have dual functions such as cytoplasmic retention of attached NF-kappa-B proteins by p100 and generation of p52 by a cotranslational processing. The proteasome-mediated process ensures the production of both p52 and p100 and preserves their independent function. p52 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. p52 and p100 are respectively the minor and major form; the processing of p100 being relatively poor. Isoform p49 is a subunit of the NF-kappa-B protein complex, which stimulates the HIV enhancer in synergy with p65. In concert with RELB, regulates the circadian clock by repressing the transcriptional activator activity of the CLOCK-ARNTL\/BMAL1 heterodimer.\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"48T","offer_id":57661815193940,"sku":"ABM217202","price":205.0,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":57661815226708,"sku":"ABM217203","price":293.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/btlab-4ed68b1a3d5e135a1cde044f69d446800526782a61fc92fdc467daf0dba68080.jpg?v=1792159222","url":"https:\/\/www.abmium.com\/de\/products\/abm217202","provider":"ABMIUM","version":"1.0","type":"link"}
