Interleukin-10: Difference between revisions

Interleukin 10 is a ternary complex that requires specific assembly for proper function. The IL-10 complex is composed of IL-10,IL-10R1,IL-10R2. The initial step is the formation of IL-10 and IL-10R1 generating a conformational change that is required for IL-10R2 to be able to associate and form the ternary complex <ref name="ref1">PMID:16982608</ref>. The completed complex activates the [http://en.wikipedia.org/wiki/JAK-STAT_signaling_pathway  JAK/STAT signaling pathway].[[Image:IL10.png|left|thumb|'''Figure 2. Sequential assembly of the ternary complex''' ]] The completion of the ternary complex is dependent on the conformational changes that occur in the N-Terminus of the helix labelled A. The conformational changes occur when the cIL-10 binds with IL-10R1. There is a positional change of about 1 angstrom at residues between Cys-12 and Leu-46.
