Nuclear factor-kappa B, also known as NFkappaB, KBF1, p110 and EBP-1, was identified as a sequence specific transcriptional activator that binds to the intronic enhancer of kappa light chain gene in B lymphocytes (1,2).
NF-kappaB is a heterodimer that consists of a 50kD DNA binding subunit (p50) and a 65 kD transactivation subunit (p65/Rel A) (3).
Both of these subunits exhibit sequence homology to the protooncogene c-Rel (4).
The p50 has an isoform called p49/p52, and both proteins are derived from the amino-terminal of precursor protein p105 (5,6) and p100 (7), respectively.
The p50/p65 heterodimer remains in the cytosol in an inactive form as a complex with its inhibitor, IkappaB.
Upon stimulation of cells by a wide variety of stimuli such as lipopolysaccharide (LPS), pro-inflammatory cytokines (interleukin-1, tumor necrosis factor), and viral infection, IkappaB is phosphorylated and degraded by proteosome.
The active NF-kappaB heterodimer is translocated into the nucleus and will induce gene expression.
