- Abstract
The crystal structure of interferon-gamma bound to the extracellular fragment of its high-affinity cell-surface receptor reveals the first view of a class-2 cytokine receptor-ligand complex. In the complex, one interferon-gamma homodimer binds two receptor molecules. Unlike the class-1 growth hormone receptor complex, the two interferon-gamma receptors do not interact with one another and are separated by 27 A. Upon receptor binding, the flexible AB loop of interferon-gamma undergoes a conformational change that includes the formation of a 3(10) helix.
