Description
Nedd4-binding partner-1 (N4BP1) has been identified as a protein interactor and a substrate of the homologous to E6AP C terminus (HECT) domain-containing E3 ubiquitinÿprotein ligase (E3), Nedd4. Here, we describe a previously unrecognized functional interaction between N4BP1 and Itch, a Nedd4 structurally related E3, which contains four WW domains, conferring substrate-binding activity. We show that N4BP1 association with the second WW domain (WW2) of Itch interferes with E3 binding to its substrates. In particular, we found that N4BP1 and p73ϫ, a target of Itch-mediated ubiquitin/proteasome proteolysis, share the same binding site. By competing with p73ϫ for binding to the WW2 domain, N4BP1 reduces the ability of Itch to recruit and ubiquitylate p73ϫ and inhibits Itch autoubiquitylation activity both in in vitro and in vivo ubiquitylation assays.
