  1. For predicted targets, the number of targets found for each miRNA of the non-homologous cluster is indicated in parentheses. *Validated using 5' RACE (rapid amplification of cDNA ends) PCR. ESTs cover the region including only miR863. The consecutive miRNAs are predicted in the intron of a protein coding gene (putative ribosomal protein).
