Data to a maximum of 2.7 Å resolution have allowed a more accurate model of the extracellular domains of the β common cytokine receptor to be determined. Structural details of the membrane-distal BC and FG loops of domain 4 and loops AB and EF of domain 1, which have been implicated in high-affinity binding, are much better defined, revealing a more compact functional epitope. X-ray diffraction has been used to produce and refine a model of the extracellular domains of the β common cytokine receptor. A minor improvement in resolution has resulted in improved electron-density maps, which have given a clearer indication of the position and stabilization of the key residues Tyr15, Phe79, Tyr347, His349, Ile350 and Tyr403 in the elbow region between domain 1 and domain 4 of the dimer-related molecule.
