Subcellular locationi
Cytoplasm and Cytosol
- Cytoplasm By similarity
Extracellular region or secreted
- Secreted By similarity
Note: The secretion is dependent on protein unfolding and facilitated by the cargo receptor TMED10; it results in protein translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) followed by vesicle entry and secretion.By similarity

Interactioni
Subunit structurei
Forms a ternary complex with ligand-binding receptor subunit IL18R1 and signaling receptor subunit IL18RAP at the plasma membrane. 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.
Interacts with cargo receptor TMED10; the interaction mediates the translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) and thereby secretion.
