U14_snoRNA

SO:0000403

Definition: U14 small nucleolar RNA (U14 snoRNA) is required for early cleavages of eukaryotic precursor rRNAs. In yeasts, this molecule possess a stem-loop region (known as the Y-domain) which is essential for function. A similar structure, but with a different consensus sequence, is found in plants, but is absent in vertebrates.

Comments and references

An evolutionarily conserved eukaryotic low molecular weight RNA capable of intermolecular hybridization with both homologous and heterologous 18S rRNA.

Change history

This timeline summarizes changes identified in SO’s GitHub commit history, including updates to labels, definitions, parent terms, synonyms, subsets, and obsoletion status. It is a best-effort reconstruction and may not include every change to a term. Since only history from GitHub is included at the moment, any term added before the migration from SVN to Git will show as being created in 2016. This will be addressed once SVN history is incorporated.
