General Information
Term small-subunit processome ID (Ontology) GO:0032040 (Gene Ontology)
Definition A large ribonucleoprotein complex that is an early preribosomal complex. In S. cerevisiae, it has a size of 80S 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.[ PubMed:12068309 PubMed:12957375 PubMed:15120992 PubMed:15590835 ]
Also Known As"small subunit processome" ; "SSU processome"
