概述	Test Principle The Non-Radioactive NFkB p50/p65 Transcription Factor Assay kit is provided in a 96-well format. During the assay, the Capture Probe, a double stranded biotinylated oligonucleotide containing the consensus sequence for NFkB binding (5'-GGGACTTTCC-3'), is mixed with cellular (nuclear) extract in the Transcription Factor Assay Buffer provided. When incubated together, the active form of NFkB contained in the nuclear extract binds to its consensus sequence. After incubation, the extract/probe/buffer mixture is then directly transferred to the streptavidin coated plate. The biotinylated double stranded oligonucleotide bound by active NFkB protein is immobilized and any inactive, unbound material is washed away. The bound NFkB transcription factor subunits, p50 and p65, are detected with specific primary antibodies, a Rabbit anti-NFkB p50 (active form) and a Rabbit anti-NFkB p65. An HRP-conjugated secondary antibody is then used for detection and provides sensitive colorimetric detection that can be read in a spectrophotometric plate reader. Included in the kit are positive cell extract, a non-specific double stranded oligonucleotide, and a specific competitor double stranded oligonucleotide. The NF kappa B Transcription Factor Assays were QC tested using nuclear extracts from human (HeLa) cells. However, because of the conservation in the NFkB DNA binding site and the fact that the antibodies contained in the kit cross react with rat and mouse NFkB, the kit is expected to work with samples from rat and mouse as well as human. For Research Use Only; Not for use in diagnostic procedures Use of this assay in NFkB-related drug discovery may be covered under U.S. Patent No. 6,150,090 and require a license from Ariad Pharmaceuticals (Cambridge, MA, USA).
背景信息	The transcription factor NFkB (Nuclear Factor kappa B) is involved in the expression and regulation of a number of important cellular and physiological processes such as growth, development, apoptosis, immune and inflammatory response, and activation of various viral promoters including human immunodeficiency virus long terminal repeats. NFkB represents a group of structurally related and evolutionarily conserved proteins related to the proto-oncogene c-Rel with five members in mammals that include Rel (cRel), RelA (p65), RelB, NFkB1 (p50 and its precursor p105), and NFkB2 (p52 and its precursor p100). NFkB/Rel proteins exist as homo- or heterodimers to form transcriptionally competent or repressive complexes. Although most NFkB dimers are activators of transcription, the p50/50 and p52/52 homodimers can repress the transcription of their target genes2, 3. The p50/p65 heterodimer of NFkB is the most abundant in cells3. A critical component in NFkB regulation is the IkB Kinase (IKK) complex3. In a majority of unstimulated cells, the NFkB transcription factors exist in their inactive form and are retained in the cytoplasm by the bound inhibitory IkB proteins. Upon stimulation by multiple inducers including viruses or cytokines, such as TNFa, IL-1, or PMA, IkBk is rapidly phosphorylated and degraded, resulting in the release of the NFkB complex, most commonly the p105/p65 heterodimer. The p105 subunit is cleaved into its active p50 form. This cleavage exposes the NLS sequence on the p50 subunit. The p50/p65 heteroduplex then translocates to the nucleus where it activates gene transcription. NFkB induces the transcription of its own inhibitor, IkBk, causing an autoregulatory mechanism of NFkB activity and generating the inactive form of NFkB. The newly formed nuclear NFkB-IkBk complexes are then exported out to the cytoplasm, thereby reestablishing the cytoplasmic pool of inactive NFkB complexes primed for another round of activation to take place. The wide variety of genes regulated by NFkB includes those encoding cytokines, chemokines, adhesion molecules, acute phase proteins, and inducible effector enzymes.

Entrez基因编号	NM_003998.2
Entrez基因汇总	NFKB1 (MIM 164011) or NFKB2 (MIM 164012) is bound to REL (MIM 164910), RELA, or RELB (MIM 604758) to form the NFKB complex. The p50 (NFKB1)/p65 (RELA) heterodimer is the most abundant form of NFKB. The NFKB complex is inhibited by I-kappa-B proteins (NFKBIA, MIM 164008 or NFKBIB, MIM 604495), which inactivate NFKB by trapping it in the cytoplasm. Phosphorylation of serine residues on the I-kappa-B proteins by kinases (IKBKA, MIM 600664, or IKBKB, MIM 603258) marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NFKB complex. Activated NFKB complex translocates into the nucleus and binds DNA at kappa-B-binding motifs such as 5-prime GGGRNNYYCC 3-prime or 5-prime HGGARNYYCC 3-prime (where H is A, C, or T; R is an A or G purine; and Y is a C or T pyrimidine).[supplied by OMIM]

UniProt编号	P19838
UniProt汇总	FUNCTION: SwissProt: Q04206 # p65 is a subunit of the nuclear factor kappa-B, a second messenger, which activates the transcription of a number of genes in multiple tissues. The inhibitory effect of I-kappa-B upon NF- kappa-B in the cytoplasm is exerted primarily through the interaction with p65. p65 shows a weak DNA-binding site which could contribute directly to DNA binding in the NF-kappa-B complex. SIZE: 551 amino acids; 60219 Da SUBUNIT: Active NF-kappa-B is a heterodimer of an about 50 kDa DNA-binding subunit and the weak DNA-binding subunit p65. Two heterodimers might form a labile tetramer. May interact with ETHE1. Binds AES and TLE1. Interacts with TP53BP2. Binds to and is phosphorylated by the activated form of either RPS6KA4 or RPS6KA5. Interacts with ING4 and this interaction may be indirect. Interacts with CARM1, USP48 and UNC5CL. SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Nuclear, but also found in the cytoplasm in an inactive form complexed to an inhibitor (I-kappa-B). PTM: Ubiquitinated, leading to its proteosomal degradation. Degradation is required for termination of NF-kappa-B response. SIMILARITY: SwissProt: Q04206 ## Contains 1 RHD (Rel-like) domain.
