Nuclear transcription factors of the NF-κB/Rel family are inhibited by IκB proteins, which inactivate NF-κB by trapping it in the cell cytoplasm. Phosphorylation of IκBs marks them out for destruction, thereby relieving their inhibitory effect on NF-κB. A cytokine-activated protein kinase complex, IKK (for IκB kinase), has now been purified that phosphorylates IκBs on the sites that trigger their degradation. A component of IKK was molecularly cloned and identified as a serine kinase. IKK turns… 
Activation of Transcription Factor NF-κB Requires ELKS, an IκB Kinase Regulatory Subunit
TLDR
ELKS likely functions by recruiting IκBα to the IKK complex and thus serves a regulatory function for IKK activation, and is likely not protected from apoptosis in response to cytokines.
How NF-κB is activated: the role of the IκB kinase (IKK) complex
TLDR
This review describes the identification of proteins in the IKK complex, and the regulation and physiological functions of IKK.
IKK-1 and IKK-2: Cytokine-Activated IκB Kinases Essential for NF-κB Activation
Activation of the transcription factor nuclear factor kappa B (NF-κB) is controlled by sequential phosphorylation, ubiquitination, and degradation of its inhibitory subunit IκB. A large multiprotein
IKK-γ is an essential regulatory subunit of the IκB kinase complex
TLDR
By using a monoclonal antibody against IKK-α, the IKK complex is purify to homogeneity from human cell lines and it is found that IKK is composed of similar amounts of IKK, α and β and two other polypeptides, for which the authors obtained partial sequences.
IKKα on Center Stage
TLDR
New roles that have been discovered for IKK α are discussed, focusing especially on its role in epidermal differentiation and on a new function of IKKα in B cell maturation.
Positive and Negative Regulation of IκB Kinase Activity Through IKKβ Subunit Phosphorylation
TLDR
IKKβ, not IKKα, is the target for proinflammatory stimuli, and once activated, IKKβ autophosphorylated at a carboxyl-terminal serine cluster, decreased IKK activity and may prevent prolonged activation of the inflammatory response.
Molecular Determinants of NF-κB-Inducing Kinase Action
TLDR
Together, these findings provide new insights into the molecular basis for TNF-α signaling, suggesting an important role for heterotypic and possibly homotypic interactions of NIK in this response.
Act1, an NF-κB-activating protein
TLDR
Act1 fails to activate NF-κB in an IL-1-unresponsive mutant cell line in which all known signaling components are present, suggesting that it interacts with an unknown component inIL-1 signaling.
The IκB kinase (IKK) and NF-κB: key elements of proinflammatory signalling
TLDR
There is strong biochemical and genetic evidence that the IKK complex, which consists of two catalytic subunits, IKKα and IKKβ, and a regulatory subunit, Ikkγ, is the master regulator of NF-κB-mediated innate immune and inflammatory responses.

IRAK: A Kinase Associated with the Interleukin-1 Receptor
TLDR
A protein kinase designated IRAK (IL-1 receptor-associated kinase) was purified, and its complementary DNA was molecularly cloned and rapidly associated with the IL-1RI complex and was phosphorylated.
TRAF6 is a signal transducer for interleukin-1
TLDR
The identification of a new TRAF family member is reported, designated TRAF6, which indicates that TRAF proteins may function as signal transducers for distinct receptor families and that TRAf6 participates in IL-1 signalling.
Activation of NF-κB by Phosphatase Inhibitors Involves the Phosphorylation of IκBα at Phosphatase 2A-sensitive Sites (*)
TLDR
Results suggest that phosphorylation of IκBα, mediated through both the TNF-α-inducible and the PP-2A-opposing kinases, may serve to target Iκbα for proteasome-mediated degradation.
Control of I kappa B-alpha proteolysis by site-specific, signal-induced phosphorylation
TLDR
Results suggest that phosphorylation at one or both of these residues is critical for activation of NF-kappa B, the transcription factor inhibited by I kappa B-alpha.
Mapping of the inducible IkappaB phosphorylation sites that signal its ubiquitination and degradation
TLDR
The mapped inducible phosphorylation sites of IkappaBalpha found that two residues, serines 32 and 36, were phosphorylated in response to either tumor necrosis factor, interleukin-1, or phorbol ester, and it is suggested that activation of a single IkappaB kinas e or closely related Ikappa B kinases is the first cr itical step in NF-kappaB activation.
In vivo stimulation of I kappa B phosphorylation is not sufficient to activate NF-kappa B
TLDR
It appears that activation of NF-kappa B requires degradation of I kappa B alpha while it is a part of the Rel cytoplasmic complex, with inducible phosphorylation of the inhibitory subunit influencing the rate of degradation.
