http://purl.uniprot.org/citations/10066435http://www.w3.org/2000/01/rdf-schema#comment"Destruction of the transcriptional inhibitor IkappaB by the ubiquitin (Ub) system is required for signal-dependent activation of the multifunctional transcriptional factor NF-kappaB, but details of this ubiquitination are largely unknown. We report here that the IkappaBalpha-ubiquitin ligase (IkappaBalpha-E3) is an SCF-like complex containing Skp1, cullin-1, and two homologous F-box/WD40-repeat proteins, betaTrCP1 and betaTrCP2. Intriguingly, all these components are cooperatively recruited to bind to a phosphorylated IkappaBalpha (pIkappaBalpha) produced by tumor necrosis factor-alpha (TNF-alpha) stimulation. IkappaBalpha-E3 bound to pIkappaBalpha catalyzed in vitro ubiquitination of pIkappaBalpha in the presence of ATP, Ub, and E1-activating and E2-conjugating enzymes. Forced expression of betaTrCP1 and betaTrCP2 resulted in dramatic augmentation of the in vitro polyubiquitination activity of IkappaBalpha-E3. These results indicate that the long-sought IkappaBalpha-E3 is an SCF-like complex consisting of multiple proteins which are coordinately assembled during phosphorylation of IkappaBalpha in response to external signals."xsd:string
