In human, IkB is an inhibitory protein that sequesters NF- kB in the cytoplasm, by masking a nuclear localization signal, located just at the C- terminal end in each of the NF- kB subunits. Phosphorylation of this residue. This activation of NF- κB in p53- depleted conditions was associated with the O- GlcNAc modification of IKKβ on various serine residues, including Ser733 – an inactivating phosphorylation site – induced by enhanced glycolysis ( Kawauchi et al.

Thus, ubiquitination provides a mechanistic link between phosphorylation and. In contrast to IKKα and IKKβ, which are constitutively expressed in most cell types, the expression of IKKi/ ε is inducible. The best well- known pathway of NF- kB activation is that mediated by the death receptor TNFR1, which starts as in the necroptosis pathway with the assembly of TRADD, RIPK1, TRAF2 and clAP1 in the lipid rafts of the plasma membrane ( complex I is formed).

Genetics Caveolin- 3 gene mutations General: Most commonly located in scaffolding domain of protein Specific mutations Arg26Gln Caveolin levels reduced 60% to 80%. This phosphorylation targets IκB- α for ubiquitination and proteosome- mediated degradation, thereby releasing NF- κB to enter the nucleus and activate a series of genes involved in the inflammatory response ( 5 ).
