IL1B

A gene on chromosome 2q14 that encodes interleukin-1B, a cytokine produced by activated macrophages as a proprotein, which is proteolytically activated by caspase 1 (CASP1/ICE). IL-1B is a key mediator of inflammation and is involved in an array of cellular activities, including cell proliferation, differentiation and apoptosis.
