[[http://www.uniprot.org/uniprot/IL1RA_HUMAN IL1RA_HUMAN]] Genetic variation in IL1RN is associated with susceptibility to microvascular complications of diabetes type 4 (MVCD4) [MIM:[http://omim.org/entry/612628 612628]]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Defects in IL1RN are the cause of interleukin 1 receptor antagonist deficiency (DIRA) [MIM:[http://omim.org/entry/612852 612852]]; also known as deficiency of interleukin 1 receptor antagonist. Autoinflammatory diseases manifest inflammation without evidence of infection, high-titer autoantibodies, or autoreactive T-cells. DIRA is a rare, autosomal recessive, genetic autoinflammatory disease that results in sterile multifocal osteomyelitis (bone inflammation in multiple places), periostitis (inflammation of the membrane surrounding the bones), and pustulosis (due to skin inflammation) from birth.<ref>PMID:19494218</ref>

== Publication Abstract from PubMed ==
 +
Interleukin-1 receptor antagonist protein (IRAP) is a naturally occurring inhibitor of the interleukin-1 receptor. In contrast to IL-1 beta, IRAP binds to the IL-1 receptor but does not elicit a physiological response. We have determined the solution structure of IRAP using NMR spectroscopy. While the overall topology of the two 153-residue proteins is quite similar, functionally critical differences exist concerning the residues of the linear amino acid sequence that constitute structurally homologous regions in the two proteins. Structurally homologous residues important for IL-1 receptor binding are conserved between IRAP and IL-1 beta. By contrast, structurally homologous residues critical for receptor activation are not conserved between the two proteins.
