Small nucleolar RNAs (snoRNAs) are one of the most numerous and well-studied groups of non-protein-coding RNAs. In complex with proteins, snoRNAs perform the two most common nucleotide modifications in rRNA: 2′-OH-methylation of ribose and pseudouridylation.

Small nucleolar RNAs (snoRNAs) are an abundant class of non-protein-coding RNAs. In association with proteins they perform two most frequent nucleotide modifications in rRNAs and some other cellular RNAs: 2'-O-ribose methylation and pseudouridylation. SnoRNAs also participate in pre-rRNA cleavage and telomerase functions.

Many small RNA species associate with the nucleolar structure. Some of these small nucleolar RNAs (snoRNAs) are required for cleavage processing of ribosomal RNA precursors. There are many pseudouridine residues and methylated riboses in mature ribosomal RNA.

Biochemistry and Cell Biology, 1995
A growing list of small nucleolar RNAs (snoRNAs) has been characterized in eukaryotes. They are transcribed by RNA polymerase II or III; some snoRNAs are encoded in the introns of other genes. The nonintronic polymerase II transcribed snoRNAs receive a trimethylguanosine cap, probably in the nucleus, and move to the nucleolus.

Small nucleolar RNAs and nucleolar proteins in Xenopus anucleolate embryos
Chromosoma, 1997We investigated the presence and localization, in the cells of anucleolate mutant embryos of Xenopus laevis, of three representative small nucleolar RNAs (snoRNAs), U3, U15 and U17, and of two nucleolar proteins, nucleolin and fibrillarin. The levels of the three snoRNAs in the anucleolate mutant are the same as in normal embryos, in contrast to 5S RNA

New functions of small nucleolar RNAs
Biochemistry (Moscow), 2013Small nucleolar RNAs (snoRNAs) are one of the most abundant and well-studied groups of non-coding RNAs. snoRNAs are mostly engaged in processing of rRNA. However, recent data indicate that snoRNAs are also involved in other processes including regulation of alternative splicing, translation and oxidative stress.

Brain-Specific Small Nucleolar RNAs
Journal of Molecular Neuroscience, 2006Small nucleolar RNAs (snoRNAs) are a group of noncoding RNAs that function mainly as guides for modification of ribosomal RNAs (rRNAs) and small nuclear RNAs (snRNAs). A subgroup of snoRNAs was found to be predominantly expressed in the brain; and interestingly, these brain-specific snoRNAs (b-snoRNAs) appear not to be involved in modification of rRNAs

Small Nucleolar RNAs Guide Ribosomal RNA Methylation
Science, 1996Two recent reports, one in Cell and one in the Journal of Molecular Biology , show that the newly described small nucleolar RNAs control the site of methylation of the ribosomal RNA (rRNA). Tollervey explains how these small RNAs accomplish this targeting and discusses the possible role of ...

Function and synthesis of small nucleolar RNAs
Current Opinion in Cell Biology, 1997Eukaryotic cells contain an extraordinarily complex population of small nucleolar RNAs (snoRNAs). During its brief lifetime, each human pre-rRNA molecule will transiently associate with approximately 150 different snoRNA species. In the past year our understanding of snoRNAs has been clarified by the recognition that the snoRNA population can be ...
