CCR5 (Chemokine-CC Motif-Receptor-5) is a member of the chemokine receptor subclass of the GPCR (G-Protein-Coupled Receptor) superfamily. It regulates leukocyte chemotaxis in inflammation and serves as a coreceptor for M-tropic (Macrophage tropic) HIV (Human Immunodeficiency Virus) entry. It serves as a functional receptor for various inflammatory CC-chemokines, including MIP1Alpha (Macrophage Inflammatory Protein-1-Alpha), MIP1Beta (Macrophage Inflammatory Protein-1-Beta), and RANTES (Regulated on Activation Normal T-Expressed ...
