Small nucleolar RNA SNORD24

U24 is a member of the C/D class of snoRNA which contain the C (UGAUGA) and D (CUGA) box motifs [1]. C/D box snoRNAs have been shown to act as methylation guides for a number of RNA targets [2,3]. U24 is encoded within an intron of the gene for ribosomal protein L7a in mammals, chicken and Fugu [4]. The U76 snoRNA is found in an intron of the uRNA host gene (UHG) growth arrest specific 5 (GAS5) transcript gene [5]. snoRNAs Z20 and U76 snoRNAs show clear similarity to U24.
