Representation of 3' UTRs for potential miRNA target genes involved in axon guidance. Each individual conserved hit between a miRNA and a target gene is marked by an annotated triangle on a conservation plot (D. melanogaster versus D. pseudoobscura) for that UTR. Red triangles indicate target site locations that are illustrated in more detail (alignment and secondary structure) below. Multiple target sites on a 3' UTR for one or more miRNAs are not uncommon and reflect cooperative regulation of transcription.
