Structural highlights
Function[IL1B_MOUSE] 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.

Publication Abstract from PubMedThe three-dimensional structure of recombinant murine interleukin-1 beta has been solved by X-ray crystallographic techniques to 2.8 A resolution and refined to a crystallographic R factor of 0.192. Although murine interleukin-1 beta crystallizes in the same space group as human interleukin-1 beta with almost identical unit cell dimensions, the packing of the molecules is quite different. The murine interleukin-1 beta structure was solved by molecular replacement using the refined structure of human interleukin-1 beta as trial structure, and found to be related to the human structure by a nearly perfect twofold rotation about the crystallographic y-axis and a 14 degrees rotation about the z-axis, with no translation. The folding of murine interleukin-1 beta is similar to that found for the human variant, consisting of 12 beta strands wrapped around a core of hydrophobic side chains in a tetrahedron-like fashion. Significant differences with respect to the human structure are seen at the N terminus and in 4 of the 11 loops connecting the 12 beta strands.
