CCR2: a seven transmembrane protein closely related to CCR1. Receptor for the MCP-1, MCP-3 and MCP-4 chemokines. Expressed at high levels in primary neutrophils and primary monocytes, and is further upregulated on neutrophil activation and during monocyte to macrophage differentiation. Transduces a signal by increasing the intracellular calcium ions level. Alternative co receptor with CD4 for HIV-1 infection. Two splice-variant isoforms have been described.
