== Function ==
[[https://www.uniprot.org/uniprot/IL10_HUMAN IL10_HUMAN]] Inhibits the synthesis of a number of cytokines, including IFN-gamma, IL-2, IL-3, TNF and GM-CSF produced by activated macrophages and by helper T-cells.

== Publication Abstract from PubMed ==
The crystal structure of human interleukin-10 (IL-10) was refined at 1.6 A resolution against X-ray diffraction data collected at 100 K with the use of synchrotron radiation. Although similar to the IL-10 structure determined previously at room temperature, this low-temperature IL-10 structure contains, in addition, four N-terminal residues, three sulfate anions, and 175 extra water molecules. Whereas the main-chain conformation is preserved, about 30% of the side chains, most of them on the protein surface, assume different conformations. A computer model of a complex of IL-10 with its two soluble receptors was generated based on the topological similarity of IL-10 to interferon-gamma. The contact region between the cytokine and each receptor shows excellent complementarity of polar and hydrophobic interactions, suggesting that the model is generally correct and should be useful in guiding mutagenesis experiments.
