Function

[CCL2_HUMAN] Chemotactic factor that attracts monocytes and basophils but not neutrophils or eosinophils. Augments monocyte anti-tumor activity. Has been implicated in the pathogenesis of diseases characterized by monocytic infiltrates, like psoriasis, rheumatoid arthritis or atherosclerosis. May be involved in the recruitment of monocytes into the arterial wall during the disease process of atherosclerosis.

Publication Abstract from PubMed

The 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.
