'''NF-kB''' or '''Nuclear Factor NF-kappa''' is a DNA transcription factor. It is involved in cellular response to stimuli. NF-kB contains a Rel homology domain (RHR) which contains 2 immunoglobulin-like subdomains which interact with the major groove of DNA. There are 5 proteins in the NF-kB family: '''NF-kB1''' (synthesized as '''p105''' and processed to '''p50'''), '''NF-kB2''' (synthesized as '''p100''' and processed to '''p52'''), '''RelA''' (or '''p65'''), '''RelB''' and '''cRel'''. I-κ-B-α is an inhibitor of NF-kB.
