Monocyte chemotactic protein (MCP-1) is also known as monocyte chemotactic and activating factor (MCAF). It is the product of the human JE gene. The precursor form of MCP-1 consists of 99 amino acids with a signal peptide sequence consisting of 23 amino-terminal amino acids. The mature form of MCP-1 has 4 cysteine residues. The first two cysteine residues are in an adjacent position C-C, which characterizes MCP-1 as a member of the chemokine ? subfamily. MCP-1 is a nonglycosylated protein consisting of 76 amino acids with a molecular weight of 8700 daltons. MCP-1 mRNA expression can be induced in monocytes/macrophages, B lymphocytes, endothelial cells and astrocytoma cells by LPS. IL-1 will induce production of MCP-1 in fibroblasts, keratinocytes, hepatoma cells, and Type II pneumocytes. In vitro, MCP-1 will act on monocytes to initiate chemotaxis, induce superoxide anion release, induce the release of lysosomal enzymes and augment cytostatic activity. In vivo, MCP-1 will induce macrophage infiltration. The MCP-1 gene contains potential binding sites for several transcription factors, including AP-1, AP-2, NF-kB, and NF-IL6.
