Abstract excerpt
The IkappaB kinase (IKK) complex is composed of three subunits, IKKalpha, IKKbeta, and IKKgamma (NEMO). While IKKalpha and IKKbeta are highly similar catalytic subunits, both capable of IkappaB phosphorylation in vitro, IKKgamma is a regulatory subunit. Previous biochemical and genetic analyses have indicated that despite their similar structures and in vitro kinase activities, IKKalpha and IKKbeta have distinct...
