Figure 1.

Complementarity between 5′ UTR of Gtx mRNA and 18S rRNA. The top sequence is that of the mouse Gtx 5′ UTR at nucleotides 127–177 (19). The lower two sequences are segments of the mouse 18S rRNA at nucleotides 700–749 and at 1088–1138 (30) with complementary nucleotides outlined in black. Potential G⋅U base pairing within these two segments is indicated by black bars positioned over uracil (U) nucleotides. The sequence of the GTX-1 and GTX-2 probes are indicated above the Gtx mRNA sequence.
