The image depicts three related structures: a comparison of coactivator and corepressor binding in PPARα, (left) active on
agonist binding, (centre) corepressor binding after helix-12 deplacement by an antagonist, and (right) direct corepressor
binding. The full figure is presented on page T10 of this issue. Credit: Fraydoon Rastinejad, Metabolic Signaling and Disease
