UTP-B complex 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.


Summary
Required for early co-transcriptional events in ribosome biogenesis, acting as an RNA chaperone to initiate ribosome assembly. May facilitate specific U3 snoRNA- 5'-external transcribed spacer (ETS) base-pairing with PWP2 bridging the interaction site. A sub-unit of the small subunit (SSU) processome, a 2.2 MDa ribonucleoprotein complex involved in the processing, assembly and maturation of nascent pre-ribosomal RNA to form the small ribosomal subunit. The SSU processome is a giant particle composed of numerous ribosome assembly factors, including the UTP-A (CPX-1409), UTP-B, UTP-C (CPX-772/CPX-771/CPX-773) and MPP10 (CPX-1893) complexes, the U3 small nucleolar ribonucleoprotein (snoRNP) and many individual proteins.
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.
