This study compared the effect of these stimuli on endogenous IkappaB kinase ( IKK ) signalsome activation and IkappaB phosphorylation/proteolysis in human monocytic cells and investigated the role of the signalsome proteins IKK-alpha , IKK-beta , NF-kappaB -inducing kinase ( NIK ), IKK-gamma ( NF-kappaB essential modulator), and IKK complex -associated protein .
 IKK complex, IKK, IKK-alpha, IKK-gamma, NF-kappaB -inducing kinase, NIK, IKK-beta, IkappaB, signalsome proteins, human monocytic cells, IkappaB kinase, IKK complex -associated protein, IkappaB, NF-kappaB, NF-kappaB
