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. (Gene Ontology, GO_0005732)
15 proteins localized to the small nucleolar ribonucleoprotein complex cellular component from the curated GO Cellular Component Annotations 2015 dataset.
