Leukemia inhibitory factor (LIF) receptor is a cell surface receptor that mediates the actions of LIF and other IL-6 type cytokines through the formation of high-affinity signaling complexes with gp130. Here we present the crystal structure of a complex of mouse LIF receptor with human LIF at 4.0 A resolution. The structure is, to date, the largest cytokine receptor fragment determined by x-ray crystallography. The binding of LIF to its receptor via the central Ig-like domain is unlike other cytokine receptor complexes that bind ligand predominantly through their cytokine-binding modules. This structure, in combination with previous crystallographic studies, also provides a structural template to understand the formation and orientation of the high-affinity signaling complex between LIF, LIF receptor, and gp130.
  Selected figure(s)  
Figure 1.
The crystal structure of the hLIF: mLIFR complex. (A) Side view of the complex illustrating the molecular surface for one complex, with receptor colored raspberry and ligand colored orange-gray. The NCS copy of the artificial dimer is shown in ribbons with receptor colored blue; ligand colored light blue; disulfide bonds colored orange, and N-linked carbohydrate colored yellow. (B) A detailed view of the receptor alone with domains and sites of posttranslational modifications labeled. Colors are as in A. (C) A domain representation of selected cytokine receptors illustrating differences in their modular domain structure.
Figure 2.
A stereo view of the hLIF:mLIFR binding interface. The receptor Ig-D4 domain secondary structure is shown as light blue ribbons. Interface residues are shown as sticks and colored yellow for receptor, salmon for ligand, and magenta for residues Pro-51, Lys-153, Phe-156 and Lys-159, previously demonstrated as essential residues for ligand binding (12).

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
