The IL-1 family is comprised of 11 structurally related ligands, including the recently re-named IL-36RA (IL-1F5), IL-36α (IL-1F6), IL-36β (IL-1F8), and IL-36γ (IL-1F9). The interaction of IL-36 ligands with the IL-1Rrp2 receptor (IL-1R6) can induce various activities, including dendritic cell maturation and activation. IL-36RA can antagonize the NF-κB signaling induced by either IL-36α, β or γ by binding to the IL-1Rrp2 receptor in a manner that prevents the initiation of functional signaling. Recombinant Murine IL-36RA is an E.coli-derived 16.9 kDa protein containing 154 amino acid residues.
