The 2.5 A structure of the CXCR4 chemokine receptor in complex with small molecule antagonist IT1t
Chemokine receptors are critical regulators of cell migration in the context of immune surveillance, inflammation, and development. The G protein-coupled chemokine receptor, CXCR4, is specifically implicated in cancer metastasis and HIV-1 infection. Here, we report five independent crystal structures of CXCR4 bound to an antagonist small molecule IT1t and a cyclic peptide CVX15 at 2.5 to 3.2 angstrom resolution. All structures reveal a consistent homodimer with an interface including helices V and VI that may be involved in regulating signaling. The location and shape of the ligand-binding sites differ from other G protein-coupled receptors (GPCRs) and are closer to the extracellular surface. These structures provide new clues about the interactions between CXCR4 and its natural ligand CXCL12 and with the HIV-1 glycoprotein gp120.
