CC -!- FUNCTION: ATP-dependent rRNA helicase required for pre-ribosomal RNA
CC processing. Involved in the maturation of the 35S-pre-rRNA and to its
CC cleavage to mature 18S rRNA. {ECO:0000250|UniProtKB:P38712}.
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 Evidence={ECO:0000250|UniProtKB:P38712};
CC -!- SUBUNIT: Interacts with the SSU processome.
CC {ECO:0000250|UniProtKB:P38712}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
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 {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the DEAD box helicase family. DDX47/RRP3
CC subfamily. {ECO:0000305}.
