Predicted to enable RNA binding activity; RNA helicase activity; and identical protein binding activity. Predicted to be involved in cellular macromolecule biosynthetic process; positive regulation of I-kappaB kinase/NF-kappaB signaling; and positive regulation of myeloid dendritic cell cytokine production. Predicted to act upstream of or within response to exogenous dsRNA and response to virus. Predicted to be located in chromosome; cytosol; and nucleoplasm. Predicted to be active in nucleolus. Orthologous to human DDX21 (DExD-box helicase 21). [provided by Alliance of Genome Resources, Apr 2022]
