Summary: Enables double-stranded RNA binding activity and identical protein binding activity. Involved in positive regulation of I-kappaB kinase/NF-kappaB signaling and positive regulation of myeloid dendritic cell cytokine production. Acts upstream of or within response to exogenous dsRNA and response to virus. Located in cytosol. Is expressed in several structures, including 1st branchial arch; early conceptus; genitourinary system; and limb. Orthologous to human DDX21 (DExD-box helicase 21).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
