Secondary structure model of human U12 snRNA. The structure is based on the earlier predicted models (21,30,31,56). SLI, Stem–Loop I; SLIIa, Stem–Loop IIa; SLIIb, Stem–Loop IIb; SLIII, Stem–Loop III; SLIII-THL, Stem–Loop III-Terminal Helix and Loop; SLIII-MH, Stem–Loop III-Middle Helix; SLIII-LH, Stem–Loop III-Lower Helix. The light shaded grey region (nucleotides 1–13, SLI) is predicted to bind U6atac snRNA and the dark shaded region (nucleotides 18–24, SLI) binds to branch site of a U12-dependent intron. Predicted Sm site is also illustrated.
