Gene Ontology Help

Box H/ACA 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.

Pseudouridine synthesis complex that converts uridine into pseudouridine at numerous specific sites within ribosomal RNAs (rRNAs) and spliceosomal small nuclear RNAs (snRNAs), isomerizing the uridine such that the ribose is subsequently attached to C5, instead of the normal N1. Pseudouridine residues may serve to stabilize the conformation of rRNAs.
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.

isomerase activity, RNA modification, rRNA processing
