| Description | NF-kappaB is a pleiotropic transcription factor present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kB 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 heterodimeric p65-p50 complex is the most abundant complex. The dimers bind at kB sites in the DNA of their target genes and the individual dimers have distinct preferences for different kB sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappaB complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappaB inhibitor (I-kB) family. In a conventional activation pathway, I-kB is phosphorylated by I-kB kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kB complex which translocates to the nucleus. NF-kB heterodimeric p65-p50 and p65-c-Rel complexes are transcriptional activators. The NF-kB p65-p65 complex appears to be involved in invasin-mediated activation of IL-8 expression. p65 shows a weak DNA-binding site which could contribute directly to DNA binding in the NF-kB complex. Source: Recombinant protein corresponding to human NF-kappaB (p65), fused to His-tag, expressed in Sf21 cells. Biological Activity: ~1ng is required for high mobility shift assay. ~5ng are required for reconstituted transcription assays Storage and Stability: Aliquot to avoid repeated freezing and thawing and store at -70°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. | ||
