Canonical Lys48- and Lys63-linked as well as non-canonical linear polyubiquitin chains are involved in receptor-mediated NF-κB activation. This study identifies c-IAP1-generated Lys11-linked chains, so far implicated only in cell-cycle control and proteasome targeting, as an additional signal in this pathway.
