The small nucleolar (sno) ribonucleic acids (RNAs) are mainly involved in the modification and processing of ribosomal RNA precursors, however, some are used to modify small nuclear RNAs (snRNAs), messenger RNAs (mRNAs) and transfer RNAs (tRNAs). They function in the form of ribonucleoproteins (snoRNPs).
