CC   -!- FUNCTION: ATP-dependent RNA helicase required for ribosome biogenesis.
CC       Involved in the release of U14 snoRNA in pre-ribosomal complexes.
CC       Required for pre-rRNA cleavage at site A2 (By similarity).
CC       {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: Interacts with the U3 and U14 snoRNAs. Associates with pre-
CC       ribosomal complexes (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus, nucleolus {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. DDX10/DBP4
CC       subfamily. {ECO:0000305}.
