EAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases which are implicated in a number of cellular processes involving RNA binding and alteration of RNA secondary structure. This gene encodes a protein containing RNA helicase-DEAD box protein motifs and a caspase recruitment domain (CARD). It is involved in viral double-stranded (ds) RNA recognition and the regulation of immune response.Synonyms: DEAD box protein 58, DKFZp434J1111, DKFZp686N19181, FLJ13599, Probable ATP-dependent RNA helicase DDX58, RIG-1, RIG-I, Retinoic acid-inducible gene 1 protein
