Nuclear factor kappa beta (NFkB) is a nearly ubiquitous pathway responsible for mediating DNA transcription, and therefore cell function. The pathway is activated by a variety of stimuli including cellular stress, cytokines, free radicals, UV radiation, oxidized LDL, and bacterial/viral infection. Activated NFkB is translocated to the nucleus where it binds to specific sequences of DNA called response elements. This DNA/NFkB complex then recruits RNA polymerase and other coactivators, which transcribe downstream DNA into mRNA, for protein synthesis.
