CCR5

chemokine (C-C motif) receptor 5 (gene/pseudogene)

This gene encodes a member of the beta chemokine receptor family, which is predicted to be a seven transmembrane protein similar to G protein-coupled receptors. This protein is expressed by T cells and macrophages, and is known to be an important co-receptor for macrophage-tropic virus, including HIV, to enter host cells. Defective alleles of this gene have been associated with the HIV infection resistance. The ligands of this receptor include monocyte chemoattractant protein 2 (MCP-2), macrophage inflammatory protein 1 alpha (MIP-1 alpha), macrophage inflammatory protein 1 beta (MIP-1 beta) and regulated on activation normal T expressed and secreted protein (RANTES). Expression of this gene was also detected in a promyeloblastic cell line, suggesting that this protein may play a role in granulocyte lineage proliferation and differentiation. This gene is located at the chemokine receptor gene cluster region. Two transcript variants encoding the same protein have been found for this gene.

This clone was generated using a stable CHO cell line with the FUT8 knockout gene. It was 100% non-fucosylated. In an in vitro cell-based ADCC assay, the afucosylated antibody clone showed significantly higher ADCC activity compared to its wild type version. The binding affinity of the non-fucosylated Fc variant antibody to Fc receptor is much higher than than the same antibody with fucosylated Fc. Robust and stable production of qualitative fully non-fucosylated therapeutic antibodies is achieved.
