Enables double-stranded RNA binding activity. Predicted to be involved in several processes, including cellular response to cytokine stimulus; regulation of cytokine production; and toll-like receptor signaling pathway. Predicted to be located in mitochondrion and ribosome. Predicted to be active in cytosol; membrane; and nucleoplasm. Predicted to colocalize with cytoplasm. Orthologous to human OAS1 (2'-5'-oligoadenylate synthetase 1). [provided by Alliance of Genome Resources, Apr 2022]
