NEGATIVE FEEDBACK:© AAASNF-κB is held inactive in the cytoplasm by three IκB isoforms. Cell stimulation activates the kinase IKK which leads to phosphorylation and degradation of IκB. This frees NF-κB to enter the nucleus and activate genes including IκBα. IκBβ and -ε are synthesized at a steady rate, allowing for complex temporal control including negative feedback. (From A. Hoffmann et al., Science, 298:1241–5, 2002.)The transcription fac
