[Chemokine (C-C Motif) Receptor 5, encoded by the CCR5 gene, is a member of the beta chemokine receptor family and a seven transmembrane protein similar to G protein-coupled receptor. This receptor is expressed by T cells and macrophages, and is an important co-receptor for macrophage-tropic virus, including HIV, to enter host cells. Defective alleles of this gene is 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 is also detected in a promyeloblastic cell line, suggesting that this protein may play a role in granulocyte lineage proliferation and differentiation.
