Ontology: Cellular Component (GO:0005732)

Definition: A ribonucleoprotein complex that contains an RNA molecule of the small nucleolar RNA (snoRNA) family and associated proteins. Most are involved in a step of processing of rRNA: cleavage, 2'-O-methylation, or pseudouridylation. The majority, though not all, fall into one of two classes, box C/D type or box H/ACA type.

Synonyms: small nucleolar ribonucleoprotein; snoRNP
