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.

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.

Non-coding RNAs: lessons from the small nuclear and small nucleolar RNAs
Nature Reviews Molecular Cell Biology, 2007Recent advances have fuelled rapid growth in our appreciation of the tremendous number, diversity and biological importance of non-coding (nc)RNAs. Because ncRNAs typically function as ribonucleoprotein (RNP) complexes and not as naked RNAs, understanding their biogenesis is crucial to comprehending their regulation and function.

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.

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 RNA Expression Profiling in Cartilage
2020Osteoarthritis (OA) presents as a change in the articular chondrocyte phenotype. The origin of the phenotype change is poorly understood. Small nucleolar RNAs (snoRNAs) direct chemical modification of other RNA substrates and are involved in endoribonucleolytic pre-rRNA processing.

Small Nucleolar RNAs: Biological Functions and Diseases
MedCommABSTRACTSmall nucleolar RNAs (snoRNAs) are a class of small RNA molecules that play a pivotal role in diverse cellular processes and are extensively implicated in the pathophysiology of various diseases. Here, we provide a comprehensive overview of snoRNAs, encompassing their classification, biogenesis, and both canonical and noncanonical functions ...

Small nucleolar RNAs and their genes in vertebrates
Russian Journal of Genetics, 2010Genes of box C/D small nucleolar RNAs (snoRNAs) were searched for in the genomes of members of all classes of vertebrates that do not belong to placental mammals. A tendency for an increase in the number of copies of snoRNA genes was observed in such vertebrates. This trend was most pronounced in anamnia (amphibians and fish).

Small nucleolar RNAs and RNA-guided post-transcriptional modification
Essays in Biochemistry, 2013snoRNAs (small nucleolar RNAs) constitute one of the largest and best-studied classes of non-coding RNAs that confer enzymatic specificity. With associated proteins, these snoRNAs form ribonucleoprotein complexes that can direct 2′-O-methylation or pseudouridylation of target non-coding RNAs.

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 ...
