Interleukin-1 receptor antagonist (IL-1ra) is a natural competitive antagonist of IL-1.

IL-1ra has the same overall beta-trefoil fold as IL-1 alpha and IL-1 beta and has a very similar hydrophobic core. However, there are a number of structural differences between the molecules, including significant differences at the open end of the beta-barrel, which has been identified in IL-1 beta as a receptor binding site. | Interleukin-1 receptor antagonist (IL-1ra) is a natural competitive antagonist of IL-1.

X-RAY STRUCTURE OF INTERLEUKIN-1 RECEPTOR ANTAGONIST AT 2.0 ANGSTROMS RESOLUTION
Overview
Interleukin-1 receptor antagonist (IL-1ra) is a natural competitive antagonist of IL-1. In order to further elucidate the mechanism by which IL-1ra binds without activating the IL-1 receptor, we have solved the crystal structure of IL-1ra at 2.0-A resolution. IL-1ra has the same overall beta-trefoil fold as IL-1 alpha and IL-1 beta and has a very similar hydrophobic core. However, there are a number of structural differences between the molecules, including significant differences at the open end of the beta-barrel, which has been identified in IL-1 beta as a receptor binding site.
