'''TYPE-1 INTERLEUKIN-1 RECEPTOR COMPLEXED WITH INTERLEUKIN-1 BETA'''<br />


==Overview==
==TYPE-1 INTERLEUKIN-1 RECEPTOR COMPLEXED WITH INTERLEUKIN-1 BETA==
Interleukin-1 (IL-1) is an important mediator of inflammatory disease. The, IL-1 family currently consists of two agonists, IL-1alpha and IL-1beta, and one antagonist, IL-1ra. Each of these molecules binds to the type I, IL-1 receptor (IL1R). The binding of IL-1alpha or IL-1beta to IL1R is an, early step in IL-1 signal transduction and blocking this interaction may, therefore be a useful target for the development of new drugs. Here we, report the three-dimensional structure of IL-1beta bound to the, extracellular domain of IL1R (s-IL1R) at 2.5 A resolution. IL-1beta binds, to s-IL1R with a 1:1 stoichiometry. The crystal structure shows that, s-IL1R consists of three immunoglobulin-like domains which wrap around, IL-1beta in a manner distinct from the structures of previously described, cytokine-receptor complexes. The two receptor-binding regions on IL-1beta, identified by site-directed mutagenesis both contact the receptor: one, binds to the first two domains of the receptor, while the other binds, exclusively to the third domain.

== Function ==
[https://www.uniprot.org/uniprot/IL1R1_HUMAN IL1R1_HUMAN] Receptor for IL1A, IL1B and IL1RN. After binding to interleukin-1 associates with the corecptor IL1RAP to form the high affinity interleukin-1 receptor complex which mediates interleukin-1-dependent activation of NF-kappa-B, MAPK and other pathways. Signaling involves the recruitment of adapter molecules such as TOLLIP, MYD88, and IRAK1 or IRAK2 via the respective TIR domains of the receptor/coreceptor subunits. Binds ligands with comparable affinity and binding of antagonist IL1RN prevents association with IL1RAP to form a signaling complex.<ref>PMID:10671496</ref>

== Publication Abstract from PubMed ==
Interleukin-1 (IL-1) is an important mediator of inflammatory disease. The IL-1 family currently consists of two agonists, IL-1alpha and IL-1beta, and one antagonist, IL-1ra. Each of these molecules binds to the type I IL-1 receptor (IL1R). The binding of IL-1alpha or IL-1beta to IL1R is an early step in IL-1 signal transduction and blocking this interaction may therefore be a useful target for the development of new drugs. Here we report the three-dimensional structure of IL-1beta bound to the extracellular domain of IL1R (s-IL1R) at 2.5 A resolution. IL-1beta binds to s-IL1R with a 1:1 stoichiometry. The crystal structure shows that s-IL1R consists of three immunoglobulin-like domains which wrap around IL-1beta in a manner distinct from the structures of previously described cytokine-receptor complexes. The two receptor-binding regions on IL-1beta identified by site-directed mutagenesis both contact the receptor: one binds to the first two domains of the receptor, while the other binds exclusively to the third domain.
