Background

Function：Pro-inflammatory cytokine primarily involved in epithelial barrier repair, polarized T-helper 1 (Th1) cell and natural killer (NK) cell immune responses (PubMed:10653850). Upon binding to IL18R1 and IL18RAP, forms a signaling ternary complex which activates NF-kappa-B, triggering synthesis of inflammatory mediators (PubMed:14528293, PubMed:25500532, PubMed:37993714). Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells and natural killer (NK) cells (PubMed:10653850). Involved in transduction of inflammation downstream of pyroptosis: its mature form is specifically released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore (PubMed:33883744)

Subcellular Localization：Cytoplasm, cytosol; Secreted

Expression：
Tissue_specificity:It is expressed in ovarian cancer but undetectable in normal ovarian epithelial cells. It is resistant to proteolytic activation by caspase-1 and -4.

Induction:In macrophages, release is increased by endocannabinoid anandamide/AEA

Isoforms & Post-Translational Modification：Q14116 has 2 isomers: Q14116-1: 22326 Da (predicted); Q14116-2: 21896 Da (predicted).
The pro-IL-18 precursor is processed by CASP1, CASP4 or CASP5 to yield its mature, active form (PubMed:15326478, PubMed:25261253, PubMed:37993712, PubMed:37993714, PubMed:9334240). The pro-IL-18 precursor features autoinhibitory interactions between the propeptide and the post-cleavage-site region, preventing recognition by the IL18R1 receptor (PubMed:37993714). Processing by CASP1, CASP4 or CASP5 induces conformational changes to generate critical receptor-binding sites (PubMed:37993714). The mature form is then secreted and released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore (PubMed:33883744, PubMed:37993714). In contrast, cleavage by CASP3 inactivates IL18 (PubMed:37993714, PubMed:9334240)

Subunit：Forms a ternary complex with ligand-binding receptor subunit IL18R1 and signaling receptor subunit IL18RAP at the plasma membrane (PubMed:14528293, PubMed:25261253, PubMed:25500532, PubMed:37993714). Mature IL18 first binds to IL18R1 forming a low affinity binary complex, which then interacts with IL18RAP to form a high affinity ternary complex that signals inside the cell (PubMed:14528293, PubMed:25261253, PubMed:25500532). Interacts with cargo receptor TMED10; the interaction mediates the translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) and thereby secretion (PubMed:32272059)
