Summary: Predicted to enable RNA binding activity; RNA helicase activity; and identical protein binding activity. Predicted to be involved in several processes, including R-loop processing; positive regulation of canonical NF-kappaB signal transduction; and positive regulation of macromolecule biosynthetic process. 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 part of B-WICH complex. Predicted to be active in nucleolus. Orthologous to human DDX21 (DExD-box helicase 21). [provided by Alliance of Genome Resources, Dec 2024]

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.
