CC   -!- FUNCTION: ATP-binding RNA helicase involved in 40S ribosomal subunit
CC       biogenesis and is required for the normal formation of 18S rRNAs
CC       through pre-rRNA processing at A0, A1 and A2 sites. Required for
CC       vegetative growth (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. DDX49/DBP8
CC       subfamily. {ECO:0000305}.
