| - | ''' | + | Human synthetic '''monocyte chemoattractant protein 1 (MCP)''' belongs to the superfamily of chemokines, which are proteins involved in immunoregulatory and inflammatory processes. The gene for CCL2 is on chromosome 17 in region 17q11.2-q12. The superfamily can be subdivided into 4 smaller groups, depending on the N-terminal arrangement of the cysteines. The CCL2<ref>PMID:8170963</ref> is also known as '''chemokine (C-C motif) ligand''' or: |

Synthesis
The protein human CCL2 has been synthesized using a combination of solid phase peptide synthesis (SPPS) and native chemical ligation (NCL). The thioester-peptide segment was synthesized using the sulfonamide safety-catch linker and 9-fluorenylmethoxycarbonyl (Fmoc) SPPS, and pseudoproline dipeptides were used to facilitate the synthesis of both CCL2 fragments. After assembly of the full-length peptide chain by NCL, a glutathione redox buffer was used to fold and oxidize the CCL2 protein. CCL2 was crystallized and the structure was determined by X-ray diffraction at 1.9-A resolution. This is probably one of the first crystal structures of a protein prepared using the sulfonamide safety-catch linker and NCL.
