Predicted to enable type II interferon receptor binding activity. Acts upstream of or within several processes, including defense response to bacterium; endothelial to hematopoietic transition; and response to virus. Predicted to be located in extracellular region. Is expressed in several structures, including axial vasculature; blood; digestive system; pleuroperitoneal region; and reproductive system. Human ortholog(s) of this gene implicated in several diseases, including allergic rhinitis; ataxia telangiectasia; autoimmune disease (multiple); eczema herpeticum; and leukemia (multiple). Orthologous to human IFNG (interferon gamma).
