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. I-κ-B-α is an inhibitor of NF-kB. 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 subunit of NF-kB) RelB cRel. Relevance NF-kB plays a critical role in cancer development and progression and may determine its response to therapy. NF-kB is a target for chemotherapeutic agents. NF-kB is a critical link between inflammation and cancer.
