|Product Overview:||IKK-alpha/beta Kinase (Human) Assay/Inhibitor Screening Assay Kit is a single-site, non-quantitative immunoassay for activities of IKK-alpha and IKK-beta. Plates are pre-coated with a substrate corresponding to recombinant IkappaB-alpha, which contains two serine residues that are phosphorylated by IKK-alpha and IKK-beta (IkappaB kinases). The detector antibody specifically detects only the phosphorylated form of IkappaB-alpha.|
|Description:||Although a number of recent studies suggest that IκB degradation and nuclear translocation of NF-κB may not be the sole regulatory events in the transcription of NF-κB-dependent genes, it has been proposed that there is the central dogma of NF-κB activation, which suggests that NF-κB is sequestered in the cytoplasm in resting cells by the inhibitory IκB proteins. In response to a variety of agonists, IκB is rapidly phosphorylated, ubiquitinated, and degraded, thus releasing NF-κB for translocation into the nucleus to initiate gene transcription. IκB kinase (IKK) is the convergence point in most signaling pathways activated by many stimuli leading to the inducible phosphorylation and degradation of IκB. IKK is a multisubunit complex that contains two catalytic subunits, IKKα and IKKβ, and the regulatory subunit IKKγ. Gene knock out studies have clearly demonstrated that IKKβ and IKKγ subunits of the IKK complex are required for NF-κB activation by all known pro-inflammatory stimuli including lipopolysaccharide (LPS), TNF, and IL-1. Thus a selective inhibitor of IKKβ would not only be of great interest as a potential anti-inflammatory agent but also as a valuable tool to understand the mechanisms regulating NF-κB activation by these inflammatory agonists.|
|Applications:||1) Screening inhibitors or activators of IKKα and IKKβ.2) Detecting the effects of pharmacological agents on IKKα and IKKβ activity.|
