GO_term: GO:0005732   

GO:0005732 Definition Any of various particulate complexes of proteins with molecules of small nucleolar RNA (any of a class of small RNAs that participate in the processing of ribosomal RNA; they contain a long stretch of sequence complementarity to conserved sequences in mature mRNA), found in the eukaryotic nucleolus. They are possibly the same as processosomes.
A complex composed of RNA of the small nucleolar RNA (snoRNA) and protein, found in the nucleolus of a eukaryotic cell. 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.
