Functions of snoRNAs
Small nucleolar RNAs (snoRNAs) constitute a class of intron-derived non-coding RNAs ranging from 60 to 300 nucleotides. snoRNAs canonically localize in the nucleolus where they play pivotal roles in pre-ribosomal RNA processing, guiding RNA modifications. Based on the type of modification they facilitate, namely methylation or pseudouridylation, they are classified into two main families—box C/D and box H/ACA snoRNAs. Investigations have revealed the unconventional synthesis and biogenesis strategies of snoRNAs, indicating more profound roles in pathogenesis than previously envisioned.
