Predicted to enable DEAD/H-box RNA helicase binding activity; RNA binding activity; and identical protein binding activity. Acts upstream of or within cellular response to exogenous dsRNA and positive regulation of type I interferon production. Located in late endosome; lysosome; and nucleus. Is expressed in early conceptus; inner cell mass; liver lobe; oocyte; and thymus primordium. Orthologous to human ZC3HAV1 (zinc finger CCCH-type containing, antiviral 1).
