NFkB p65 (Transcription Factor p65, Nuclear Factor NF-kappa-B p65 Subunit, Nuclear Factor of kappa Light Polypeptide Gene Enhancer in B-cells 3, RELA, NFKB3)

NFkB was identified as a sequence specific transcriptional activator that binds to the intronic enhancer of kappa light chain gene in B lymphocytes. NFkB is a heterodimer that consists of a 50kD DNA binding subunit (p50) and a 65kD transactivation subunit (p65/RelA). Both of these subunits exhibit sequence homology to the protooncogene c-Rel. The p50/p65 heterodimer remains in the cytosol in an inactive form as a complex with its inhibitor, IkB. Upon stimulation of cells by a wide variety of stimuli such as lipopolysaccharide (LPS), pro-inflammatory cytokines, and viral infection. IkB is phosphorylated and degraded by proteosome. The active NFkB heterodimer is translocated into the nucleus and induces gene expression.\n\nApplications:\nSuitable for use in Western Blot, Immunoprecipitation and Immunohistochemistry.
