 6-153 7.10e-53

beta-trefoil domain found in interleukin-18 (IL-18) and similar proteins; IL-18, also called Iboctadekin, or interferon gamma-inducing factor, or IFN-gamma-inducing factor, or interleukin-1 gamma, or IL-1 gamma, is a proinflammatory cytokine primarily involved in polarized T-helper 1 (Th1) cell and natural killer (NK) cell immune responses. Upon binding to IL18R1 and IL18RAP, it forms a signaling ternary complex which activates NF-kappa-B, triggering synthesis of inflammatory mediators. IL-18 works synergistically with IL12/interleukin-12 to induce IFN-gamma synthesis from Th1 cells and natural killer (NK) cells. IL-18 contains a beta-trefoil domain, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

 6-153 3.45e-25

beta-trefoil domain found in the interleukin-1 (IL-1) family of cytokines; The IL-1 family of cytokines comprises 11 members, including 7 pro-inflammatory agonists (IL-1alpha, IL-1beta, IL-18, IL-33, IL-36alpha, IL-36beta, IL-36gamma) and 4 defined or putative antagonists (IL-1R antagonist (IL-1Ra), IL-36Ra, IL-37, and IL-38) exerting anti-inflammatory activities. These members can have complimentary or distinct biological functions. All family members share a common structure at the C-terminus, which is comprised by of a typical beta-trefoil fold consisting of 12-beta-strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.
