Predicted to enable cytokine activity and interleukin-18 receptor binding activity. Involved in several processes, including cellular response to hormone stimulus; positive regulation of cell population proliferation; and positive regulation of cytokine production. Located in apical plasma membrane; cytoplasm; and extracellular space. Used to study brain edema; fatty liver disease; heart disease; status epilepticus; and vasculitis. Biomarker of several diseases, including cardiac arrest; ischemia (multiple); lung disease (multiple); perinatal necrotizing enterocolitis; and urinary tract infection. Human ortholog(s) of this gene implicated in several diseases, including Kawasaki disease; allergic rhinitis; autoimmune disease (multiple); biliary atresia; and hepatitis B. Orthologous to human IL18 (interleukin 18). [provided by Alliance of Genome Resources, Apr 2022]
