small nucleolar RNAs tagged posts

Image: Based upon conserved snoRNA sequence elements, this large population of guide RNAs has been divided into two major families designated the box C/D and the box H/ACA snoRNAs. The primary function of the box C/D snoRNAs is to guide 2′-O-methylation of targeted rRNA nucleotides while the box H/ACA snoRNAs direct the conversion of specific uridine residues to pseudouridine.

Scientists have discovered unexpected functions of small nucleolar RNAs (snoRNAs) that explain the cause of some genetic diseases and cancers. However, it is not clear how the change in snoRNA expression could lead to these diseases. Using RNA sequencing and molecular biology techniques, researchers found snoRNAs not only modify ribosomes, but can also regulate alternative splicing...
