'''IL-1 RECEPTOR TYPE 1 COMPLEXED WITH ANTAGONIST PEPTIDE AF10847'''<br />


==Overview==
==IL-1 RECEPTOR TYPE 1 COMPLEXED WITH ANTAGONIST PEPTIDE AF10847==
Interleukin (IL-1)alpha and IL-1beta are important mediators of, inflammation. The binding of IL-1 to interleukin-1 receptor (IL-1R) type 1, is the initial step in IL-1 signal transduction and therefore is a, tempting target for anti-inflammatory therapeutics. To advance our, understanding of IL-1R1 binding interactions, we have determined the, structure of the extracellular domains of IL-1R1 bound to a 21-amino acid, IL-1 antagonist peptide at 3.0-A resolution. The antagonist peptide binds, to the domain 1/2 junction of the receptor, which is a conserved binding, site for IL-1beta and IL-1 receptor antagonist (IL-1ra). This co-crystal, structure also reveals that considerable flexibility is present in IL-1R1, because the carboxyl-terminal domain of the receptor is rotated almost 170, degrees relative to the first two domains of the receptor compared with, the previously solved IL-1R1.ligand structures. The structure shows an, unexpected binding mode for the peptide and may contribute to the design, of smaller IL-1R antagonists.

== 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 (IL-1)alpha and IL-1beta are important mediators of inflammation. The binding of IL-1 to interleukin-1 receptor (IL-1R) type 1 is the initial step in IL-1 signal transduction and therefore is a tempting target for anti-inflammatory therapeutics. To advance our understanding of IL-1R1 binding interactions, we have determined the structure of the extracellular domains of IL-1R1 bound to a 21-amino acid IL-1 antagonist peptide at 3.0-A resolution. The antagonist peptide binds to the domain 1/2 junction of the receptor, which is a conserved binding site for IL-1beta and IL-1 receptor antagonist (IL-1ra). This co-crystal structure also reveals that considerable flexibility is present in IL-1R1 because the carboxyl-terminal domain of the receptor is rotated almost 170 degrees relative to the first two domains of the receptor compared with the previously solved IL-1R1.ligand structures. The structure shows an unexpected binding mode for the peptide and may contribute to the design of smaller IL-1R antagonists.
