Chronic inflammation has been strongly associated with tumor progression, but the underlying mechanisms remain elusive. Here we demonstrate that E3 ligase Itch and deubiquitinase Cyld form a complex via the interaction through ‘WW-PPXY’ motifs. The Itch-Cyld complex sequentially cleaved K63-linked ubiquitin chains and catalyzed K48-linked ubiquitination on the kinase Tak1 to terminate inflammatory tumor necrosis factor signaling. Reconstitution of wild-type Cyld but not mutant Cyld(Y485A), which cannot associate with Itch, blocked the sustained Tak1 activation and proinflammatory cytokine production by Cyld−/− bone marrow-derived macrophages. Itch or Cyld deficiency resulted in chronic production of tumor-promoting cytokines by the tumor-associated macrophages and aggressive growth of lung carcinoma. Thus, we have uncovered an Itch-Cyld mediated regulatory mechanism in innate inflammatory cells.
