The IKK complex: an integrator of all signals that activate NF-kappaB?

Trends Cell Biol. 2000 Apr;10(4):129-33. doi: 10.1016/s0962-8924(00)01729-3.


The NF-kappaB family of transcription factors plays a crucial role in the immune, inflammatory and apoptotic responses. These proteins are normally found in the cytoplasm, retained by interaction with an inhibitory molecule called IkappaB. Activation of the NF-kappaB signalling cascade results in phosphorylation and degradation of IkappaB, allowing nuclear translocation of the NF-kappaB complexes. The recent identification of a high-molecular-weight complex containing two kinases and a regulatory subunit has led to a flurry of new results that shed light on some of the most complex mechanisms contributing to the exquisite regulation of NF-kappaB activity.
