General Information

Term

sno(s)RNA-containing ribonucleoprotein complex

ID (Ontology)

GO:0005732 (Gene Ontology)

Definition

A ribonucleoprotein complex that contains an RNA molecule of the snoRNA family and associated proteins. Many are involved in a step of processing of rRNA molecules: cleavage, 2'-O-methylation, or pseudouridylation, but other RNA types can be targets as well. The majority fall into one of two classes, box C/D type or box H/ACA type, which are conserved across eukaryotes and archaea. Other members include the telomerase RNA and the ribonuclease MRP RNA.[ ISBN:0879695897 PubMed:17284456 ]
