Description

IL-1 receptor antagonist (IL-1ra) was originally isolated from the urine of patients with monocytic leukemia and has also been purified from adherent monocytes. The protein shows 26% amino acid homology to IL-1 beta and 19% homology to IL-1 alpha. It will compete with either factor for receptor binding, but does not interact with either one. Human IL-1ra will bind to both types of IL-1 receptor (I and II) on human cells. In mouse, IL-1RII does not bind IL-1ra.
