Disease

[IL1RA_HUMAN] Genetic variation in IL1RN is associated with susceptibility to microvascular complications of diabetes type 4 (MVCD4) [MIM: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: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.^[1]

Function

[IL1RA_HUMAN] Inhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. Has no interleukin-1 like activity. Binds functional interleukin-1 receptor IL1R1 with greater affinity than decoy receptor IL1R2; however, the physiological relevance of the latter association is unsure.^[2]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

We report the crystallization of samples of a recombinant preparation of human interleukin-1 receptor antagonist protein (IRAP) and solution of the crystal structure by isomorphous replacement methods. Crystals were obtained by the hanging-drop vapor-diffusion method at 277 K from solutions of PEG 4000 containing sodium chloride, dithiothreitol and PIPES [sodium piperazione-N,N'-bis(2-ethanesulfonate)] buffer at pH 7.0. Crystals appear within about a week and grow as truncated tetragonal bipyramids to 0.3-0.6 mm on an edge. X-ray diffraction data from these crystals specify space group P4(3)2(1)2 and unit-cell dimensions of a = b = 72.35(26), c = 114.7(8) A and Z = 16 (two molecules per asymmetric unit). Fresh crystals diffract to about 2.3 A resolution. The search for heavy-atom derivatives has produced two, potassium gold cyanide and trimethyl lead chloride, as same-site, single-site derivatives. Inspection of an electron-density map at 4 A resolution calculated with these derivatives confirms that the IRAP molecule is a member of the interleukin-1 structural family.
