Human IL36G is a secreted member of the IL1 family, one of three IL36 genes in humans. The IL1 family members display a conserved 12 b-strand and a b-trefoil configuration, likely due to ascendance from a mutual ancenstral gene. IL36G is expressed primarily in tissues containing epithelial cells, and is both intracellular and secreted. Its primary receptor appears to be a combination of IL-1rp2 and IL-1Racp, the first being primarily expressed on dendritic cells and the second being more widely expressed. Binding of IL36G ligands to this receptor is one of the factors which induces dendritic cell maturation. Its expression is also an agonist for pro-inflammatory cytokines through the NF-kB and Map kinase pathways. Recombinant human IL36G migrates as an 18.9 kDa protein on SDS-PAGE and shares approximately 52% sequence identity with mouse IL36G.
