VIRAL CHEMOKINE BINDING PROTEIN M3 FROM MURINE GAMMAHERPESVIRUS68 IN COMPLEX WITH THE P8A VARIANT OF CC-CHEMOKINE MCP-1VIRAL CHEMOKINE BINDING PROTEIN M3 FROM MURINE GAMMAHERPESVIRUS68 IN COMPLEX WITH THE P8A VARIANT OF CC-CHEMOKINE MCP-1

FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe M3 protein encoded by murine gamma herpesvirus68 (gamma HV68) functions as an immune system saboteur by the engagement of chemoattractant cytokines, thereby altering host antiviral inflammatory responses. Here we report the crystal structures of M3 both alone and in complex with the CC chemokine MCP-1. M3 is a two-domain beta sandwich protein with a unique sequence and topology, forming a tightly packed anti-parallel dimer. The stoichiometry of the MCP-1:M3 complex is 2:2, with two monomeric chemokines embedded at distal ends of the preassociated M3 dimer. Conformational flexibility and electrostatic complementation are both used by M3 to achieve high-affinity and broad-spectrum chemokine engagement. M3 also employs structural mimicry to promiscuously sequester chemokines, engaging conservative structural elements associated with both chemokine homodimerization and binding to G protein-coupled receptors. Structural basis of chemokine sequestration by a herpesvirus decoy receptor.,Alexander JM, Nelson CA, van Berkel V, Lau EK, Studts JM, Brett TJ, Speck SH, Handel TM, Virgin HW, Fremont DH Cell. 2002 Nov 1;111(3):343-56.
