TNFRI has been recently shown to activate NF-kappaB through association with TRADD , RIP , and TRAF2 ; activation of the NF-kappaB -inducing kinase ( NIK ); activation of the IkappaB alpha kinases ( IKKalpha and IKKbeta ); and phosphorylation of IkappaB alpha .
 protein: NIK; protein: NF-kappaB; protein: TRADD; protein: IKKalpha; protein: RIP; protein: NF-kappaB; protein: TNFRI; protein: IKKbeta; protein: NF-kappaB -inducing kinase; protein: IkappaB alpha kinases; protein: TRAF2; protein: IkappaB alpha
