<unk>  (nuclear factor-kappa B) is a protein complex which is a transcription factor.  <unk>  is found in all cell types and is involved in cellular responses to stimuli such as stress, cytokines, free radicals, ultraviolet irradiation, and bacterial or viral antigens. <unk>  plays a key role in regulating the immune response to infection.  Consistent with this role, incorrect regulation of<unk>  has been linked to cancer, inflammatory and autoimmune diseases, septic shock, viral infection and improper immune development.<unk>  has also been implicated in processes of synaptic plasticity and memory.
