In enzymology, an IκB kinase (EC 2.7.11.10) is an enzyme that catalyzes the chemical reaction: . ATP + IκB protein ADP + IκB phosphoprotein. Thus, the two substrates of this enzyme are ATP and IκB protein, whereas its two products are ADP and IκB phosphoprotein.
IKK-β is an enzyme that serves as a protein subunit of IκB kinase, which is a component of the cytokine-activated intracellular signaling pathway involved in triggering immune responses. IKK's activity causes activation of a transcription factor known as Nuclear Transcription factor kappa-B or NF-κB .
This activity allows subsequent homodimerization and nuclear translocation of the IRF3 leading to transcriptional activation of pro-inflammatory and antiviral genes including IFNB. In order to establish such an antiviral state, IKBKE forms several different complexes whose composition depends on the type of cell and cellular stimuli.
Oxidative stress is the most powerfully specific stress activating p38 MAPK. [7] Abnormal activity (higher or lower than physiological) of p38 has been implicated in pathological stresses in several tissues, that include neuronal, [8] [9] [10] bone, [11] lung, [12] cardiac and skeletal muscle, [13] [14] red blood cells, [15] and fetal tissues.

NF-kappa-B essential modulator (NEMO) also known as inhibitor of nuclear factor kappa-B kinase subunit gamma (IKK-γ) is a protein that in humans is encoded by the IKBKG gene. NEMO is a subunit of the IκB kinase complex that activates NF-κB. [5] The human gene for IKBKG is located on the chromosome band Xq28. [6]
Serine/threonine-protein kinase, Intestinal cell kinase or ICK [5] is an enzyme that in humans is encoded by the ICK gene. [ 6 ] [ 7 ] Eukaryotic protein kinases are enzymes that belong to a very extensive family of proteins which share a conserved catalytic core common with both serine/threonine and tyrosine protein kinases .
This activity is actually inhibited by glutamate and other conditions that elevate intraneuronal calcium. In the final analysis, the role of NF-κB in neurons remains opaque due to the difficulty of measuring transcription in cells that are simultaneously identified for type.
