CCL7 (MCP-3, C-C motif chemokine 7, Monocyte chemoattractant protein 3, Monocyte chemotactic protein 3,MCP-3, NC28, Small-inducible cytokine A7, CCL7, MCP3, SCYA6, SCYA7)

Monocyte chemotactic protein 3 (MCP3)(CCL7) is secreted by monocytes and certain tumer cell lines. It is a chemoattractant for monocytes and other leukocytes. MCP3 binds and signals through several cell surface receptors including CCR1, CCR2, CCR3, and appears to be an antagonist for CCR5.
