CC -!- FUNCTION: ATP-dependent RNA helicase involved in 40S ribosomal subunit
CC biogenesis. Required for the processing and cleavage of 35S pre-rRNA at
CC sites A0, A1, and A2, leading to mature 18S rRNA.
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: Associates in the nucleolus with the 60S and pre-60S ribosomal
CC subunits. {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. DDX18/HAS1
CC subfamily. {ECO:0000305}.
