90S preribosome Gene Set

Dataset	GO Cellular Component Annotations 2025
Category	structural or functional annotations
Type	cellular component
Description	A large ribonucleoprotein complex considered to be the earliest preribosomal complex. In S. cerevisiae, it has a size of 90S and consists of the 35S pre-rRNA, early-associating ribosomal proteins most of which are part of the small ribosomal subunit, the U3 snoRNA and associated proteins.
