Visualizing allosteric inhibition.


Structures of two chemokine receptor proteins in complex with small molecules reveal a previously unknown binding pocket that could be a drug target for treating a range of diseases involving this receptor family.

A family of cell-membrane proteins known as G-protein-coupled receptors mediates transmembrane signal transduction. One subset of this family is the chemokine receptors, which regulate cell migration and whose activation has been implicated in a range of diseases, including immune disorders and cancer. But finding drugs that inhibit these receptors has been challenging. Two papers online in Nature1, 2 now describe crystal structures of two different chemokine receptors in complex with small-molecule inhibitors. Two of these antagonists bind to pockets near to the receptors' intracellular surfaces, pointing to a previously unidentified pathway that can be targeted for drug discovery.
