CC -!- FUNCTION: ATP-binding RNA helicase involved in the biogenesis of 60S
CC ribosomal subunits. Binds 90S pre-ribosomal particles and dissociates
CC from pre-60S ribosomal particles after processing of 27SB pre-rRNA.
CC Required for the normal formation of 18S rRNA through the processing of
CC pre-rRNAs at sites A0, A1 and A2, and the normal formation of 25S and
CC 5.8S rRNAs through the processing of pre-rRNAs at sites C1 and C2.
CC {ECO:0000250|UniProtKB:P25808}.
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:P25808};
CC -!- SUBUNIT: Component of pre-60S ribosomal complexes.
CC {ECO:0000250|UniProtKB:P25808}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleolus
CC {ECO:0000250|UniProtKB:P25808}.
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. DDX55/SPB4
CC subfamily. {ECO:0000305}.
