Figure 3. Structure of U8 snoRNA. A) Secondary structure of mature U8 snoRNA. Sequence and structure taken from [Citation21]. Orange circles refer to naturally occurring SNPs found in [Citation13]. Orange triangles refer to nucleobase insertions. Yellow circle is trimethylguanosine cap. Green box and black box refer to C and D box motifs, respectively. Purple hexagons are LSm motif. Boxed nucleotides refer to pre-U8 snoRNA 3′–extension from [Citation42]. Image generated using Varna [Citation44]. B) Three-dimensional computational model of U8 snoRNA. Sequence and secondary structure from [Citation21]. Model generated using RNAComposer [Citation45,Citation46]. Colour scheme corresponds to those mapped onto A.
