SOCS1 does not bind to any pTyr sites on the interferon gamma receptor. a Schematic diagrams of the IFN-α, ɣ and IL-2 receptors. All intracellular tyrosines are shown. b Table showing the binding affinities of human SOCS1 for each IFN-ɣ and IL-2 receptor phosphopeptide. Errors represent standard deviation from three independent experiments. c Representative ITC curves are shown for the four IL-2R phosphopeptides that bind to SOCS1 with sub-micromolar affinity
