Secondary structures of U5 snRNA isoforms. The secondary structures were generated based on the canonical human U5 snRNA secondary structure (Branlant et al. 1983). (Lowercase letters) The conserved 5′ region found in all U5 snRNAs, (boxed nucleotides) the conserved 11-nt region, (gray underlined letters) putative Sm binding sites, (bold capital letters) the unique 3′ variable regions that differ in length and structure. The asterisk indicates where the conserved 5′ region would be found in each U5 RNA variant. The name of each variant refers to its chromosomal location: U5 canonical is located in K03096; 23D, in AE003581; 34A, in AE003639; 63BC, in AE003477; 35D, in AE003648; 14B, in AE003501; 38ABa and 38ABb, in AE003664.
