ABSTRACT:
Compounds that inhibit ubiquitin-mediated proteolysis of phosphorylated IκB by interfering, directly or indirectly, with the ability of β-TrCP/E3RS to engage in protein-protein association involving hnRNP-U, are useful as drugs for treating conditions associated with NF-κB activation. Cellular and non-cellular screening methods for identifying such compounds are based on monitoring the association/dissociation of β-TrCP/E3RS.
