| Intruduction: | Human C5a anaphylatoxin chemotactic receptor 1 (C5AR1, also named as CD88) gene encodes a receptor for the chemotactic and inflammatory peptide anaphylatoxin C5a. The ligand interacts with at least two sites on the receptor: a high-affinity site on the extracellular N terminus, and a second site in the trans-membrane region which activates downstream signaling events. Receptor activation stimulates chemotaxis, granule enzyme release, intracellular calcium release and superoxide anion production. As C5a is thought to activate myeloid-derived suppressor cells and thereby make the tumor microenvironment immunosuppressive, so blocking C5a / C5AR1 signaling pathway might be a good therapeutic target for cancer immunotherapy. Four fragments of human C5AR1 extracellular domain were jointed together using small GGGS link sequence. This fusion protein cDNA (20 – 253 aa) was constructed with codon optimization gene synthesis and expressed with a human alpha Fetal Protein N-terminal (AFPn) -His-TEV cleavage site Tag (217aa) fusion at its N-terminal in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified. |
