This type of modifying RNA is located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. It is known as a small nucleolar RNA (snoRNA). SNORA79 was identified by computational screening and its expression in mouse experimentally verified by Northern blot and primer extension analysis.[1] It belongs to the H/ACA box class of snoRNAs as it has the predicted hairpin-hinge-hairpin-tail structure and the conserved H/ACA-box motifs.[2] SNORA79 is proposed to guide the pseudouridylation of residue U31 in U6 snRNA.[3] Pseudouridylation is the isomerisation of the nucleoside uridine to the different isomeric form pseudouridine.
