Enables CCR2 chemokine receptor binding activity. Involved in angiogenesis; inflammatory response; and monocyte chemotaxis. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in central nervous system and retina. Human ortholog(s) of this gene implicated in several diseases, including Henoch-Schoenlein purpura; aggressive periodontitis; autoimmune disease (multiple); gastrointestinal system cancer (multiple); and tuberculosis (multiple). Orthologous to human CCL2 (C-C motif chemokine ligand 2) and CCL8 (C-C motif chemokine ligand 8). [provided by Alliance of Genome Resources, Apr 2022]
