    ..The Imp4 superfamily is composed of five individual families (Imp4, Rpf1, Rpf2, Brx1, and Ssf) that all possess the sigma(70)-like motif, a eukaryotic RNA binding domain with prokaryotic origins...

    ..Mutations in the WD40 motifs of Ytm1 disrupt binding to Erb1, destabilize the heterotrimer, and delay pre-rRNA processing and nuclear export of preribosomes. Nevertheless, 66S preribosomes lacking Ytm1 remain otherwise intact. ..
