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.
Gene References into Functions
  1. This is the first study in an equine model to establish a dosing/redosing protocol, as well as examine the Nab response to capsid and supports further clinical investigation to determine the clinical efficacy of scAAVIL-1ra to treat osteoarthritis. PMID: 25902762
  2. Expression of IL-1RN in the endometrium is likely regulated by estradiol and progesterone and suggest that IL-1RN regulates the degree of IL-1 signal transduction and thereby plays an important role in the establishment of equine pregnancy. PMID: 19157767
Subcellular Location Secreted.
Protein Families IL-1 family
