IKK-β also known as inhibitor of nuclear factor kappa-B kinase subunit beta is a protein that in humans is encoded by the IKBKB (inhibitor of kappa light polypeptide gene enhancer in B-cells, kinase beta) gene.

Function

[edit]
Main article: IκB kinase

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. Activated IKK-β phosphorylates a protein called the inhibitor of NF-κB, IκB (IκBα), which binds NF-κB to inhibit its function. Phosphorylated IκB is degraded via the ubiquitination pathway, freeing NF-κB, and allowing its entry into the nucleus of the cell where it activates various genes involved in inflammation and other immune responses.

Clinical significance

[edit]

IKK-β plays a significant role in brain cells following a stroke.[5] If NF-κB activation by IKK-β is blocked, damaged cells within the brain stay alive, and according to a study performed by the University of Heidelberg and the University of Ulm, the cells even appear to make some recovery.[6]

Inhibition of IKK and IKK-related kinases has been investigated as a therapeutic option for the treatment of inflammatory diseases and cancer.[7] The small-molecule inhibitor of IKK2 SAR113945, developed by Sanofi-Aventis, was evaluated in patients with knee osteoarthritis.[8]
