IL-36Ra/IL-1F5 is a highly and a specific antagonist of the IL-1 receptor-related protein 2-mediated response to IL-36alpha (IL-1F6), IL-36beta (IL-1F8) and IL-36gamma (IL-1F9). These cytokines bind to IL-36R (IL-1Rrp2) and IL-1RAcP, activating similar intracellular signals as IL-1. IL-36Ra inhibits the production of proinflammatory cytokines, including IL-12, IL-1beta, IL-6, TNF-alpha and IL-23 induced by IL-36 in BMDC and CD4 T cells. Skin and dendritic cells are target of the IL-36 interleukins leading to a Th1 response. Recently mutations that affect the levels and the activity of IL-36Ra have been found in patients with pustular psoriasis, leading to enhanced production of inflammatory cytokines (IL-8 in particular) by keratinocytes.

Biological Activity:
Inhibits the IL-6 induced expression of IL-36alpha (IL-1F6), IL-36beta (IL-1F8), and IL-36gamma (IL-1F9) in BMDCs. 1ug/ml of IL-36Ra inhibits the activity of 10 ng to 100 ng/ml of the agonists.

IL36Ra (mouse) (aa 2-156) is untagged.
