Definition

Small nucleolar RNAs (snoRNAs) are short non-coding RNAs enriched in the nucleolus as components of small nucleolar ribonucleoproteins. They guide ribose methylation and pseudouridylation of rRNAs and snRNAs, and a subgroup regulate excision of rRNAs from rRNA precursor transcripts. snoRNAs may also guide rRNA acetylation and tRNA methylation, and regulate mRNA abundance and alternative splicing. 31828325
