OTULIN (OTU deubiquitinase with linear linkage specificity) removes linear polyubiquitin from proteins that have been modified by LUBAC (linear ubiquitin chain assembly complex) and is critical for preventing auto-inflammatory disease1,2 and embryonic lethality during mouse development3. Here we show that OTULIN promotes rather than counteracts LUBAC activity by preventing its auto-ubiquitination with linear polyubiquitin. Thus, knock-in mice that express catalytically inactive OTULIN, either constitutively or selectively in endothelial cells, resembled LUBAC-deficient mice4 and died midgestation as a result of cell death mediated by TNFR1 (tumour necrosis factor receptor 1) and the kinase activity of RIPK1 (receptor-interacting protein kinase 1). Inactivation of OTULIN in adult mice also caused pro-inflammatory cell death. Accordingly, embryonic lethality and adult auto-inflammation were prevented by the combined loss of cell death mediators: caspase 8 for apoptosis and RIPK3 for necroptosis. Unexpectedly, OTULIN mutant mice that lacked caspase 8 and RIPK3 died in the perinatal period, exhibiting enhanced production of type I interferon that was dependent on RIPK1. Collectively, our results indicate that OTULIN and LUBAC function in a linear pathway, and highlight a previously unrecognized interaction between linear ubiquitination, regulators of cell death, and induction of type I interferon.
