Summary of IL1RN

This gene encodes a protein that modifies a variety of interleukin 1 related immune and inflammatory responses. It is associated with higher risk for bone fractures and gastric cancer (R). 

The Function of 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.
