CC -!- FUNCTION: ATP-binding RNA helicase involved in the biogenesis of 60S
CC ribosomal subunits (PubMed:2408148, PubMed:25579579). Binds 90S pre-
CC ribosomal particles and dissociates from pre-60S ribosomal particles
CC after processing of 27SB pre-rRNA (PubMed:21825077). Required for the
CC normal formation of 18S rRNA through the processing of pre-rRNAs at
CC sites A0, A1 and A2, and the normal formation of 25S and 5.8S rRNAs
CC through the processing of pre-rRNAs at sites C1 and C2
CC (PubMed:9769101). Also required for recruitment of NOG2 to pre-
CC ribosomes (PubMed:22735702). {ECO:0000269|PubMed:21825077,
CC ECO:0000269|PubMed:22735702, ECO:0000269|PubMed:2408148,

CC -!- SUBCELLULAR LOCATION: Nucleus, nucleolus {ECO:0000269|PubMed:14562095,
CC ECO:0000269|PubMed:9769101}.
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 -!- MISCELLANEOUS: Present with 5740 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
