Open channel blockers are very different in their chemistry and structure. Now GLIC, a bacterial model for pentameric ligand-gated channels, is used to investigate the structural basis of open channel block. The work identifies two extended interaction sites, with large blockers binding to the center of the membrane and small blockers binding to the narrow intracellular region.
