Figure 7.

Enlarged computer-generated version (Zuker, 2003) of the 3′ UTR of StBEL5 from nucleotide (nt) 2,215 to 2,674 (arrows). Three types of conserved motifs are highlighted: poly-U (solid line), a unique UAGUA motif (double-striped line), and the polypyrimidine tract, CUUCU (dotted line). The enlarged figure (at right) is derived from the Mfold model of full-length StBEL5 RNA (at left and Fig. 3A). Full-length StBEL5 RNA is 2,716 nucleotides in length. The 3′ UTR begins at nucleotide 2,215 (designated by the lower arrow). It should be noted, however, that the existence of these conserved motifs does not validate their function.
