Predicted to enable 2'-5'-oligoadenylate synthetase activity; ATP binding activity; and double-stranded RNA binding activity. Predicted to be involved in several processes, including defense response to other organism; negative regulation of viral genome replication; and positive regulation of cytokine production. Predicted to act upstream of or within RNA catabolic process; interleukin-27-mediated signaling pathway; and response to bacterium. Predicted to be located in perinuclear region of cytoplasm. Predicted to be active in cytosol; membrane; and nucleoplasm. Orthologous to human OAS2 (2'-5'-oligoadenylate synthetase 2). [provided by Alliance of Genome Resources, Apr 2022]
