Nuclear factor kappa B (NF-kB) is a ubiquitous transcription factor and an essential mediator of gene expression during activation of immune and inflammatory responses.
NF-kB mediates the expression of a great variety of genes in response to extracellular stimuli including IL-1, TNFa, and bacteria product LPS.
NF-kB is associated with IkB proteins in the cell cytoplasm, which inhibit NF-kB activity.
The long-sought IkB kinase (IKK), which phosphorylates IkB, and mediates IkB degradation and NF-kB activation, was recently identified by several laboratories (1-5).
IKK is a serine protein kinase, and the IKK complex contains alpha and beta subunits (IKKa and IKKb).
IKKa and IKKb interact with each other and both are essential for the NF-kB activation.
IKKa specifically phosphorylates IkB-a.
IKKa is expressed in a variety of human tissues.
This polyclonal antibody can be used for detection of IKKa by Western blot at 1:500 to 1:1000 dilution.
Whole cell lysate from Jurkat cells can be used as positive control and an 85kD band should be detected.
It has no cross response to IKKb or IKKg.
