HUMAN IL-10 / IL-10R1 COMPLEX
Contents |
Overview
Interleukin 10 (IL-10) is a dimeric cytokine that plays a central role in, suppressing inflammatory responses. These activities are dependent on the, interaction of IL-10 with its high-affinity receptor (IL-10R1). This, intermediate complex must subsequently recruit the low-affinity IL-10R2, chain before cell signaling can occur. Here we report the 2.9 A crystal, structure of IL-10 bound to a soluble form of IL-10R1 (sIL-10R1). The, complex consists of two IL-10s and four sIL-10R1 molecules. Several, residues in the IL-10/sIL-10R1 interface are conserved in all IL-10, homologs and their receptors. The data suggests that formation of the, active IL-10 signaling complex occurs by a novel molecular recognition, paradigm where IL-10R1 and IL-10R2 both recognize the same binding site on, IL-10.
