Background

IL-1ra was originally isolated from the urine of patients with monocytic leukemia and has also been purified from adherent monocytes. The naturally-occurring, fully glycosylated form has an apparent molecular weight of about 25,000 Daltons. 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 receptors (I and II) on human cells, but reportedly will not block binding to the type II receptor on murine pre-B cell lines. IL-1ra has been shown to block the inflammatory responses induced by IL-1 both in vitro and in vivo. Human, mouse and rat IL-1ra all share approximately 80% homology with porcine IL-1ra.
