DESCRIPTION

Also known as IL1B_HUMAN, IL1B, IL1F2. Potent proinflammatory cytokine. Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production. Promotes Th17 differentiation of T-cells. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells (PubMed:10653850). Plays a role in angiogenesis by inducing VEGF production synergistically with TNF and IL6 (PubMed:12794819). Monomer. In its precursor form, weakly interacts with full-length MEFV; the mature cytokine does not interact at all (PubMed:17431422). Interacts with integrins ITGAV:ITGBV and ITGA5:ITGB1; integrin-binding is required for IL1B signaling (PubMed:29030430). Interacts with cargo receptor TMED10; the interaction is direct and is required for the secretion of IL1B mature form (PubMed:32272059). Interacts with HSP90AB1; the interaction facilitates cargo translocation into the ERGIC (PubMed:32272059). Interacts with HSP90B1; the interaction facilitates cargo translocation into the ERGIC (PubMed:32272059).
