Background
Monocyte Chemotactic Protein-1 (MCP-1), also known as CCL2, MCAF and TDCF, is a heparin-binding small protein belonging to the C-C motif chemokine family. Human MCP-1 cDNA encodes a 99 amino acid (aa) precursor consisting of a 23 aa signal peptide and a 76 aa mature protein with a receptor binding and dimerization N-terminus and a glycosaminoglycan (GAG)-binding C-terminus. Mature human MCP-1 is 57% aa identical to the mouse ortholog (JE). Multiple proteolytically processed isoforms of MCP-1, such as the N-terminally truncated forms of 71 aa and 72 aa residues, as well as the c-terminally truncated form of 69 aa residues. MCP-1 is secreted by many different cell types, including endothelial cells (EC), monocytes, fibroblasts, vascular smooth muscle cells, mast cells, and astrocytes.
The MCP-1 receptors are three G-protein-coupled receptors: CCR2, CCR4 and D6/CCBP2. Primarily, MCP-1 plays a chemotactic role in monocytes and basophils. Clinically, MCP-1 has been implicated in pathogeneses of several diseases characterized by monocytic infiltrates, such as psoriasis, rheumatoid arthritis and atherosclerosis.
