Murine JE/MCP-1

Member of CC chemokine family that uses the CCR2 receptor for chemo-attracting monocytes to the site of release (also called monocyte chemoattractant protein - 1). This coding sequence lacks the heavily glycosylated C-terminus present in the wild-type protein and has been shown to have a increased chemotactic potency^[1][2]. The protein can be expressed recombinantly in a prokaryotic system because of its lack of glycosylation and post-translational modifications.

Biology

Mcp-1 belongs to the CC family of chemokines and is recognised by the CCR2 receptors found on murine monocytes. Due to its inherent homology to human CCL2, it acts as a effective chemokine for human moncytes as well. The N-term region of the protein has been implicated in receptor binding and any fusion to this terminal might result in decreased activity. In both mice and humans, the chemokine is produced by a wide variety of cell types including endothelial,fibroblasts, epithelial, smooth muscle, mesangial, astrocytic, monocytic, and microglial cells^[2]. Apart from monocytes, CCL2 has also been shown to chemoattract NK cells and T cells with comparatively lesser efficacy.
