miRNA-dependent regulation of CrebA, Eip74 and ttk. Each panel shows at top the distribution of the miRNA target sites in the CrebA (A), Eip74 (B) and ttk (C) 3' UTRs. For panels A and C, the vertical bars above the line indicate sites for miR-92b, while vertical bars below the line indicate sites for miR-312. Luciferase expression data are presented as in Fig. 1.
