Predicted to enable double-stranded RNA adenosine deaminase activity; double-stranded RNA binding activity; and tRNA-specific adenosine deaminase activity. Predicted to be involved in RNA processing and adenosine to inosine editing. Predicted to be active in cytoplasm and nucleolus. Orthologous to human ADARB2 (adenosine deaminase RNA specific B2 (inactive)). [provided by Alliance of Genome Resources, Apr 2022]
