CC -!- FUNCTION: ATP-dependent RNA helicase required for 60S ribosomal subunit
CC synthesis. Involved in efficient pre-rRNA processing, predominantly at
CC site A3, which is necessary for the normal formation of 25S and 5.8S
CC rRNAs (By similarity). {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 -!- 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. DDX5/DBP2
CC subfamily. {ECO:0000305}.
