Small ribosomal subunit processome Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.

Mediates the early stages of maturation of the small ribosomal subunit by coupling RNA folding to subsequent RNA cleavage and processing steps. A 47S precursor transcript contains coding segments for the small ribosomal subunit (18S) and large ribosomal subunit (28S and 5.8S) and regulatory regions including the 5' external transcribed spacer (5' ETS). The SSU processome binds to the 5' ETS and cleaves the precursor transcript at site A1, which separates the 5′ ETS and 18S segments. and then drives the transition toward a pre-40S particle.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
