WebNational Center for Biotechnology Information WebEach snoRNA molecule acts as a guide for only one (or two) individual modifications in a target RNA. In order to carry out modification, each snoRNA associates with at least four protein molecules in an RNA/protein complex referred to as a small nucleolar ribonucleoprotein (snoRNP).

WebThe snoRNA molecule contains an antisense element (a stretch of 10–20 nucleotides ), which are base complementary to the sequence surrounding the base ( nucleotide) targeted for modification in the pre-RNA molecule. This enables the … WebWithin snoRNPs, snoRNAs complement with rRNA sequences and guide the modification of 2’ O-methylation or pseudouridylation. RNPs that catalyze 2’ O-methylation are called C/D box RNPs, while those that catalyze pseudouridylation are termed H/ACA box RNPs [1].
