derives_from U14_snoRNA U14 snoRNA 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. SO:0000403 sequence An evolutionarily conserved eukaryotic low molecular weight RNA capable of intermolecular hybridization with both homologous and heterologous 18S rRNA.
