    Herpesvirus-8 macrophage inflammatory protein-II (vMIP-II) binds a uniquely wide spectrum of chemokine receptors. We report the X-ray structure of vMIP-II determined to 2.1 A resolution. Like RANTES, vMIP-II crystallizes as a dimer and displays the conventional chemokine tertiary fold. We have compared the surface topology and electrostatic potential of vMIP-II to those of eotaxin-1, RANTES, and MCP-3, three CCR3 physiological agonists with known three-dimensional structures. Surface epitopes identified on RANTES to be involved in binding to CCR3 are mimicked on the eotaxin-1 and MCP-3 surface. However, the surface topology of vMIP-II in these regions is markedly different. The results presented here indicate that the structural basis for interaction with the chemokine receptor CCR3 by vMIP-II is different from that for the physiological agonists eotaxin-1, RANTES, and MCP-3. These differences on vMIP-II may be a consequence of its broad-range receptor recognition capabilities.
