U5 small nuclear ribonucleoprotein 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.

Non-coding RNA containing complex that is involved in mRNA splicing. U5 snRNP is delivered to the forming spliceosome as part of the U4/U6 x U5 tri-snRNP complex (CPX-25). The spliceosome is a highly dynamic structure, assembled by sequential binding and release of the small nuclear RNAs and protein factors which removes intronic sequence from pre-mRNA. During spliceosome activation several subunits dissociate, but U5 is necessary for both trans-esterification steps during splicing.
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.
