Interleukin-1 receptor, type I
Interleukin-33 receptor

Interleukin-1 receptor, type II
Quaternary Structure Comments
IL1RAP is an accessory protein subunit of the functional receptors for IL-1, IL-33 and IL-36. It is a component in three signalling pathways that involve six IL-1 family cytokines (IL-1α, IL-1β, IL-33, IL-36α, IL-36β and IL-36γ).

Protein Comments
An anti-IL1RAP monoclonal antibody (CAN04, nidanilimab) has been designed by Cantargia as a novel immunomodulator and it is being evaluated for potential antineoplastic efficacy in patients with solid malignant tumours (Phase 1/2 NCT03267316). CAN04 activates the immune system's killer cells and blocks proliferation signals that promote tumour growth. MAB-hR3, an antagonistic monoclonal antibody that targets IL1RAP inhibits signalling via all three of the signalling pathways in which IL1RAP is a co-receptor, is predicted to offer a novel broad spectrum anti-inflammatory agent for potential treatment of autoimmune and inflammatory diseases, with preclinical evidence provided by a mouse equivalent to MAB-hR3 which attenuates inflammation in in vivo models of inflammatory diseases that are driven by distinct subsets of the IL-1 family cytokines [1].
