Crystal structure of the CXCR4 chemokine receptor in complex with a small molecule antagonist IT1t in I222 spacegroupCrystal structure of the CXCR4 chemokine receptor in complex with a small molecule antagonist IT1t in I222 spacegroup

Publication Abstract from PubMed

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.
