Protein Variants Comment Organism
DELTA307-384 mutant protein consisting of a deletion of the ubiquitin-like domain that is present only in IKKbeta fails to activate NFkappaB in response to IL-1 or TNF. Deletion mutant is incorporated into the IKK complex, indicating that this domain is not important for the intermolecular interaction between the IKKs and NEMO. Deletion mutant strongly associate with the NF-kappaB p65 subunit in the absence or presence of stimuli, whereas wild-type IKKbeta can not be detected in a complex with p65. This indicates that the to propose a model in which the ubiquitin-like domain plays a role in release of NF-kappaB following IkappaBalpha phosphorylation Homo sapiens
L353X L353 within the ubiquitin-like domain is necessary to activate NF-kappaB-dependent gene expression. However, the L353 mutant is able to phosphorylate IkappaBalpha suggesting that the defect in NF-kappaB activation is not at the level of inhibition of IkappaB degradation Homo sapiens
