There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105\/p50), and NF-κB2 (p100\/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus (9-11). Following IKK-mediated phosphorylation of p105 NF-κB at multiple sites (Ser921, 923, 927, and 932) on its carboxy-terminus, SCF\/β-TrCP mediated processing produces the 50 kDa active form p50 (12,13).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCVID12; DKFZp686C01211; DNA binding factor KBF1; DNA-binding factor KBF1; EBP-1; KBF1; MGC54151; NF-kappa-B; NF-kappa-B1; NF-kappaB; NF-kappabeta; NF-kB; NF-kB1; NFkappaB; NFKB-p105; NFKB-p50; NFKB1; NFKB1\/p105; NFKB1\/p50; nuclear factor kappa B subunit 1; nuclear factor kappa-B DNA binding subunit; Nuclear factor NF-kappa-B p105 subunit; Nuclear factor NF-kappa-B p50 subunit; Nuclear factor of kappa light polypeptide gene enhancer in B-cells 1; p105; p50\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nMW (kDa): 50 Active form. 120 Precursor\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46797574078633,"sku":"12540T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-12540t","provider":"Iright","version":"1.0","type":"link"}
