FUNCTIONAL IMPLICATIONS OF INTERLEUKIN-1BETA BASED ON THE THREE-DIMENSIONAL STRUCTURE
Contents |
Overview
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.
