Role of Has1 RNA helicase in ribosome biogenesis in yeast S. cerevisiae


ABSTRACT: The RNA helicase Has1 is involved in the biogenesis of both small and large ribosomal subunit. How it performs these separate roles is not fully understood. We analysed a detailed composition of RNA-protein complexes purified via Has1.

The RNA helicase Has1 is involved in the biogenesis of both small and large ribosomal subunits. How it performs these separate roles is not fully understood. Here we provide evidence that at least two molecules of Has1 are temporarily present at the same time in 90S pre-ribosomes. We identified multiple Has1 binding sites in the 18S, 5.8S and 25S rRNAs. We show that while the Has1 catalytic activity is not required for binding to 5.8S/25S region in pre-rRNA, it is essential for binding to 18S si  ...[more]
