The crystal structure of recombinant human interleukin-4 (rhuIL-4) was initially determined at 3.5-A resolution by multiple isomorphous replacement techniques and subsequently refined to a resolution of 2.35 A by simulated annealing. The final crystallographic R-factor, based on all data in the range 6.0-2.35 A (7470 reflections), is 0.232. Bond lengths and bond angles in the molecule have root mean square deviations from ideal values of 0.016 A and 2.4 degrees, respectively. The overall…

The Crystal Structure of Murine Leukemia Inhibitory Factor a
TLDR
The structure of murine leukemia inhibitory factor is determined by X-ray crystallography at 2.0 A resolution and the mainchain fold conforms to the four alpha-helix bundle topology previously observed for several members of the hematopoietic cytokine family.
The solution structure of the F42A mutant of human interleukin 2.
TLDR
The structural differences observed in this mutant IL-2 suggest that the replacement of Phe42 with Ala causes the re-orientation of neighbouring side-chains that are also involved in binding the alpha-chain of the receptor.
The Existence of Multiple Conformers of Interleukin-21 Directs Engineering of a Superpotent Analogue*
TLDR
The high resolution three-dimensional structure of human interleukin (hIL)-21 has been resolved by heteronuclear NMR spectroscopy and an hIL-21 analog was designed to stabilize the region around helix C through the introduction of a segment grafted from hil-4.
Crystals of a 1:1 complex between human interleukin-4 and the extracellular domain of its receptor alpha chain.
TLDR
The crystals are isomorphous to that of the complex with normal IL-4 and therefore can be used to solve the crystallographic phase problem by the method of multiple anomalous diffraction (MAD).
Solution structure of synthetic peptides corresponding to the C-terminal helix of interleukin-6.
TLDR
Two synthetic peptides corresponding to the C-terminal 19 residues of human and murine interleukin-6 have been synthesized and their structures in solution investigated using high-resolution 1H-NMR spectroscopy, suggesting that such peptide analogues should be useful starting points in the design of peptide agonists and antagonists of interleukoethanol.
Structure and dynamics of the human granulocyte colony-stimulating factor determined by NMR spectroscopy. Loop mobility in a four-helix-bundle protein.
TLDR
Examination of the protein's relaxation behavior shows that the G-CSF backbone has a well-defined structure of limited conformational flexibility in helices, and the long loop connecting helices C and D exhibits substantial fast internal motion compared to the overall rotational correlation time of the whole molecule.
Comparison of four independently determined structures of human recombinant interleukin–4
TLDR
Four independent structures of human interleukin–4, two determined by nuclear magnetic resonance techniques and two by X–ray diffraction, have been compared in detail to answer some general questions about the accuracy of protein structure determination by these two techniques.
Solution structure of human IL-13 and implication for receptor binding.
TLDR
Based on the available structural and mutational data, an IL-13/IL-4Ralpha model and a sequential mechanism for forming the signaling heterodimer is proposed forIL-13.
Stoichiometry of the complex of human interleukin‐4 with its receptor
Hematopoietic cytokines: Similarities and differences in the structures, with implications for receptor binding
TLDR
Crystal and NMR structures of helical cytokines–interleukin‐4 (IL‐4), granulocyte‐macrophage colony‐stimulating factor (GM‐CSF), and interleukIn‐2 ( IL‐2)–have been compared and patches of positively charged residues on the surfaces of helices C and D of IL‐4 may be responsible for the interactions with the negatively charged residues found in the complementary parts of the IL‐ 4 receptors.
