The turnover of interleukin-1β, a cytokine that plays important roles in both physiologic and pathologic inflammatory processes, is regulated by proteolytic maturation of the pro-form and by ubiquitin-mediated degradation. Here authors identify the specific ubiquitin E3 ligases that form an active complex with UBE2L3, a ubiquitin conjugating enzyme, that target pro-IL-1β for proteasomal breakdown.
