The function of Ensembl gene identifier ENSG00000108691 (CCL2, C-C motif chemokine ligand 2) is as follows. Acts as a ligand for C-C chemokine receptor CCR2 (PubMed:10529171, PubMed:10587439, PubMed:9837883). Signals through binding and activation of CCR2 and induces a strong chemotactic response and mobilization of intracellular calcium ions (PubMed:10587439, PubMed:9837883). Exhibits a chemotactic activity for monocytes and basophils but not neutrophils or eosinophils (PubMed:8195247, PubMed:8627182, PubMed:9792674). May be involved in the recruitment of monocytes into the arterial wall during the disease process of atherosclerosis (PubMed:8107690). {ECO:0000269|PubMed:10529171, ECO:0000269|PubMed:10587439, ECO:0000269|PubMed:8107690, ECO:0000269|PubMed:8195247, ECO:0000269|PubMed:8627182, ECO:0000269|PubMed:9792674, ECO:0000269|PubMed:9837883}.
