The ubiquitylation of IL-1β limits its cleavage by caspase-1 and targets it for proteasomal degradation

Hyperactivation of inflammasome-induced IL-1β can cause immunopathology and is a feature of autoinflammatory diseases. Here, the authors show how ubiquitination of IL-1β limits its activity by targeting it for proteasomal degradation and preventing its cleavage by caspase-1.
