Nuclear receptor ligands and cofactor recruitment: is there a coactivator "on deck"?
Farnesoid X receptor (FXR) is a bile acid sensor that regulates lipid homeostasis. New structural data suggest that, unlike other nuclear receptors, FXR contains a second coactivator binding site and binds bile acids with the steroid backbone flipped head to tail, both of which have important functional ramifications.
