CC   -!- FUNCTION: Anti-inflammatory antagonist of interleukin-1 family of
CC       proinflammatory cytokines such as interleukin-1beta/IL1B and
CC       interleukin-1alpha/IL1A. Protects from immune dysregulation and
CC       uncontrolled systemic inflammation triggered by IL1 for a range of
CC       innate stimulatory agents such as pathogens.
CC       {ECO:0000250|UniProtKB:P25085}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P18510}.
CC   -!- SIMILARITY: Belongs to the IL-1 family. {ECO:0000305}.
