Interleukin 17 (IL-17) cytokines play a crucial role in mediating inflammatory and autoimmune diseases. A unique intracellular signaling domain termed SEFIR is found within all IL-17 receptors (IL-17Rs) as well as the key adaptor protein Act1. SEFIR-mediated protein-protein interaction is a crucial step in IL-17 cytokine signaling. Here, the 2.3 A resolution crystal structure of the SEFIR domain of IL-17RA, the most commonly shared receptor for IL-17 cytokine signaling, is reported. The structure includes the complete SEFIR domain and an additional alpha-helical C-terminal extension, which pack tightly together to form a compact unit. Structural comparison between the SEFIR domains of IL-17RA and IL-17RB reveals substantial differences in protein topology and folding. The uniquely long insertion between strand betaC and helix alphaC in IL-17RA SEFIR is mostly well ordered, displaying a helix (alphaCC'ins) and a flexible loop (CC'). The DD' loop in the IL-17RA SEFIR structure is much shorter; it rotates nearly 90 degrees with respect to the counterpart in the IL-17RB SEFIR structure and shifts about 12 A to accommodate the alphaCC'ins helix without forming any knots. Helix alphaC was identified as critical for its interaction with Act1 and IL-17-stimulated gene expression. The data suggest that the heterotypic SEFIR-SEFIR association via helix alphaC is a conserved and signature mechanism specific for IL-17 signaling. The structure also suggests that the downstream motif of IL-17RA SEFIR together with helix alphaC could provide a composite ligand-binding surface for recruiting Act1 during IL-17 signaling.
