+==FUNCTIONAL IMPLICATIONS OF INTERLEUKIN-1BETA BASED ON THE THREE-DIMENSIONAL STRUCTURE==
-The molecular structure of interleukin-1 beta, a hormone-like cytokine with roles in several disease processes, has been determined at 2.0 A resolution and refined to a crystallographic R-factor of 0.19. The framework of this molecule consists of 12 antiparallel beta-strands exhibiting pseudo-3-fold symmetry. Six of the strands make up a beta-barrel with polar residues concentrated at either end. Analysis of the three-dimensional structure, together with results from site-directed mutagenesis and biochemical and immunological studies, suggest that the core of the beta-barrel plays an important functional role. A large patch of charged residues on one end of the barrel is proposed as the binding surface with which IL-1 interacts with its receptor.

+== Function ==
+[https://www.uniprot.org/uniprot/IL1B_HUMAN IL1B_HUMAN] Produced by activated macrophages, IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells.<ref>PMID:3920526</ref>
