| Introduction | Transcription factors of the nuclear factor κB (NF-κB)/Rel family play a pivotal role in inflammatory and immune responses. There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins. NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression. NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus.PMA-induced NF-kappaB transcriptional activity is dependent on the region between amino acids 442 and 470, suggesting a role for one or more of the potential phosphorylation sites (Ser457, Thr458, Thr464, or Ser468) in this region. T-cell costimulation and Calyculin A have both been shown to increase Ser468 phosphorylation. IKKβ (but not IKKα) and GSK-3β both target this site (14, 15), which appears to have a negative regulatory role not involving inhibition of nuclear translocation after TNFα or IL-1β stimulation. |
