Description
Interleukin-1 (IL-1) is a family of cytokines that play a central role in the regulation of immune and inflammatory responses to infections or sterile insults. IL-1α and IL-1β are the first two members discovered in this family, which are the products of distinct genes recognizing the same cell surface receptors. IL-1α and IL-1β are structurally related polypeptides that show approximately 25% homology at the amino acid level. Both proteins are produced by a wide variety of cells in response to stimuli such as those produced by inflammatory agents, infections, or microbial endotoxins. The proteins are synthesized as 31 kDa precursors that are subsequently cleaved into proteins with molecular weights of approximately 17.5 kDa. The specific protease responsible for the processing of IL-1β is interleukin 1β-converting enzyme (ICE)/caspase-1. Mature human and mouse IL-1β share approximately 75% amino acid sequence identity where human IL-1β has been found to be active on murine cell lines. Creative Biolabs Interleukin (IL)-1β, murine, produced in CHO cells, is a non-glycosylated polypeptide chain containing 152 amino acids and having a molecular mass of 17,400 Da.
