CRYSTAL STRUCTURE OF IP-10 T-FORM
Overview
We have determined the structure of wild-type IP-10 from three crystal, forms. The crystals provide eight separate models of the IP-10 chain, all, differing substantially from a monomeric IP-10 variant examined previously, by NMR spectroscopy. In each crystal form, IP-10 chains form conventional, beta sheet dimers, which, in turn, form a distinct tetrameric assembly., The M form tetramer is reminiscent of platelet factor 4, whereas the T and, H forms feature a novel twelve-stranded beta sheet. Analytical, ultracentrifugation indicates that, in free solution, IP-10 exists in a, monomer-dimer equilibrium with a dissociation constant of 9 microM. We, propose that the tetrameric structures may represent species promoted by, the binding of glycosaminoglycans. The binding sites for several, IP-10-neutralizing mAbs have also been mapped.
