ATP-binding RNA helicase that plays a role in maturation of the small ribosomal subunit in ribosome biogenesis (PubMed:30582406). Required for the release of the U3 snoRNP from pre-ribosomal particles (PubMed:30582406). Plays a role in early testis development (PubMed:31287541, PubMed:31337883). Probably also plays a role in brain development (PubMed:31256877). ATP + H2O = ADP + H(+) + phosphate Interacts with UTP14A. Expressed in the fallopian tube, ovary, uterus and testis. Also expressed in the brain. The disease may be caused by variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry. Belongs to the DEAD box helicase family. DEAH subfamily.
