Summary: Enables double-stranded RNA binding activity. Involved in positive regulation of canonical NF-kappaB signal transduction and positive regulation of myeloid dendritic cell cytokine production. Acts upstream of or within response to exogenous dsRNA and response to virus. Located in cytoplasmic stress granule; cytosol; and mitochondrion. Is expressed in several structures, including 1st branchial arch; blastocyst; central nervous system; early embryo; and genitourinary system. Orthologous to human DDX1 (DEAD-box helicase 1).

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.
