C/D box snoRNAs have been shown to act as methylation guides for a number of RNA targets. U24 is encoded within an intron of the gene for ribosomal protein L7a in mammals, chicken and Fugu.
C/D box snoRNAs have been shown to act as guides for methylation of various RNA targets. The U24 snoRNA is encoded within an intron of the gene for ribosomal protein L7a in mammals, birds, and pufferfish, indicating a conserved function across species.
