CC   -!- FUNCTION: ATP-dependent RNA helicase involved nonsense-mediated mRNA
CC       decay and ribosome biogenesis through rRNA processing. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13;
CC   -!- SUBUNIT: Associates with polysomes. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC   -!- DOMAIN: The Q motif is unique to and characteristic of the DEAD box
CC       family of RNA helicases and controls ATP binding and hydrolysis.
CC   -!- SIMILARITY: Belongs to the DEAD box helicase family. DDX5/DBP2
CC       subfamily. {ECO:0000305}.
