Product Detail	IL1RA is a member of the Interleukin 1 cytokine family. This protein inhibits the activities of Interleukin 1, alpha (IL1A) and Interleukin 1, beta (IL1B), and modulates a variety of Interleukin 1 related immune and inflammatory responses. This gene and five other closely related cytokine genes form a gene cluster spanning approximately 400 kb on chromosome 2. A polymorphism of this gene is reported to be associated with increased risk of osteoporotic fractures and gastric cancer. Four alternatively spliced transcript variants encoding distinct isoforms have been reported. Function: Inhibits the activity of interleukin-1 by binding to eceptor 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. Subcellular Location: Isoform 1: Secreted. Isoform 2, 3, 4: Cytoplasm. Tissue Specificity: The intracellular form of IL1RN is predominantly expressed in epithelial cells. DISEASE: Microvascular complications of diabetes 4 (MVCD4) [MIM:612628]: 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. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. Interleukin 1 receptor antagonist deficiency (DIRA) [MIM:612852]: A rare autoinflammatory disease of skin and bone resulting in sterile multifocal osteomyelitis, periostitis, and pustulosis from birth. The term autoinflammatory disease describes a group of disorders characterized by attacks of seemingly unprovoked inflammation without significant levels of autoantibodies and autoreactive T-cells. Note=The disease is caused by mutations affecting the gene represented in this entry.
