question: Which are the subunits of the IkB protein kinase (IKK)?
answer: Proinflammatory NF-kappaB activation requires the IkappaB (inhibitor of NF-kappaB) kinase (IKK) complex that contains two catalytic subunits named IKKalpha and IKKbeta and a regulatory subunit named NF-kappaB essential modulator (NEMO).Additional components may exist, transiently or permanently, but their characterization is still unsure.
