I?B kinase ? (IKK?) is a catalytic subunit of the I?B kinase (IKK) complex, a key mediator of NF-?B activation.{57847} It is composed of an N-terminal kinase domain, which contains an activation loop with two serine residues, Ser 177 and Ser 181, that are subject to phosphorylation, a ubiquitin-like domain, a scaffold dimerization domain, and a C-terminal domain that binds the regulatory subunit IKK?, also known as NF-?B essential modifier (NEMO). IKK? is ubiquitously expressed and localizes in the cytoplasm to the IKK complex, which mediates NF-?B activation in response to numerous stimuli, including inflammatory cytokines and B- and T cell receptor engagement, as well as LPS and growth factors. Upon cellular stimulation, the TAK1-TAB complex phosphorylates and activates IKK?, which induces phosphorylation and degradation of the NF-?B inhibitory protein I?B, permitting NF-?B nuclear translocation and the transcription of numerous genes involved in inflammation, immunity, and cell survival and proliferation.{57848,57847} IKK? has roles in several pathological conditions, including cancer and inflammatory diseases, such as rheumatoid arthritis.{57847} IKBKB mutations have been found in patients with severe combined immunodeficiency (SCID).{57849} Cayman’s IKK? (human, recombinant) protein can be used for enzyme activity assays.
