IL1RN (human)

Overview
IL1RN 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. The intracellular form of IL1RN is predominantly expressed in epithelial cells. 4 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
