Preferred Label : rna, small nucleolar;
MeSH definition : Small nuclear RNAs that are involved in the processing of pre-ribosomal RNA in the
nucleolus. Box C/D containing snoRNAs (U14, U15, U16, U20, U21 and U24-U63) direct
site-specific methylation of various ribose moieties. Box H/ACA containing snoRNAs
(E2, E3, U19, U23, and U64-U72) direct the conversion of specific uridines to pseudouridine.
Site-specific cleavages resulting in the mature ribosomal RNAs are directed by snoRNAs
U3, U8, U14, U22 and the snoRNA components of RNase MRP and RNase P.;
